The global economic system relies heavily on the U.S. dollar as a reserve currency, and once U.S. influence declines dramatically, international trade chains are at risk of breaking down. Many countries have longined their security architectures with U.S. military aid and technology transfer, a model based on the monopoly pattern formed after the Cold War.
Currently, the total amount of U.S. foreign aid has exceeded trillions of dollars, of which its dependence on specific allies is particularly prominent. From a geostrategic perspective, this recession is not a single event, but a cumulative effect, including increased debt burdens, internal political divisions, and increased external challenges. Large countries such as Russia and China have built alternative paths through energy and commodity exports to reduce exposure to the dollar system.
As a key player in the Middle East, Israel’s defense system is highly integrated with U.S. technology. By 2025, the U.S. has provided more than $217 billion in military support to Israel, mainly for the procurement and maintenance of F-35. These fighter jets are equipped with advanced hidden coating and sensor networks, in sharp contrast to Iran’s F-4 jets, which still rely on the 1970s design, mobility and electronic warfare capabilities behind.
Although the Israeli army is small, it receives tens of billions of dollars in US loans, often converted into grants to help it develop its Iron Dome missile defense system. The system has an interception rate of up to 90%, but relies on U.S. satellite intelligence sharing. Once U.S. aid is discontinued, Israel will have to bear maintenance costs independently, and a supply chain disruption will result in fighter aircraft availability falling by more than 30%.
In the past, Israel won in the Six-Day War with speed, and now faced with the human advantage of the Arab and Persian Coalition forces, the enduring war will expose its industrial undercapacity. The total population of the Arab countries hundreds of millions, can mobilize million-level troops, by consuming tactics to gradually dismantle the Israeli 100,000 regular troops.
Although Iran and Syria are old in equipment, in recent years, they have improved the accuracy of missiles through localized transformation, closing the gap with Israel's high-tech advantages. This transformation stems from independent research and development driven by U.S. sanctions. Compared with Israel's external dependence, it shows the resilience of the localization path.
Japan's core equipment depends on U.S. licensed production. By 2025, Japan's defense budget reaches $55 billion, mainly for upgrading F-15 and F-16 fighter jets, these fighter aircraft radar systems and missile interfaces require U.S. technical support. Standard 2 and Standard 3 missile maintenance agreements directly bind the U.S. supply chain, Japan's domestic production is limited, the annual production is less than 10 warships, the tank production line is small and cannot support a mass conflict.
In the past, Japan restricted military expansion through a peaceful constitution, and now gradually increases electronic warfare equipment within the framework of the US-Japan Alliance, but the industrial chain is incomplete and reserve mobilization is inefficient. Once the United States recesses, Japan needs to switch to domestic research and development, such as expanding submarine cable protection technology, but unlike before, from defense-oriented to regional projective power construction.
This kind of promotion requires huge investment, and material reserves and transportation systems become bottlenecks. Compared with the large-scale industries of Russia or China, although Japan's refined manufacturing is advanced, it is easy to run out of inventory in a war of attrition. Although the South Korean navy has 331 ships, it is not as deep as Britain's strategic depth in the North Atlantic. Similar problems in Japan will amplify its vulnerability.
The Korean military industry is essentially a assembly system, with its K-2 tanks based on the U.S. M-1 Abrams design, provided with core modules by General Motors, shrinking versions reducing weight but sacrificing protection.K-9 is self-introduced from Europe, and the fire control system relies on U.S. compatibility agreements.
In 2025, South Korea's defense budget will be US$44 billion for local satellite research and development, but intelligence and medium-and long-range operations still rely on the U.S. satellite network. The 500,000 troops are highly dependent on the field of electronic warfare. Without assistance, the failure rate will increase, and system compatibility problems will occur frequently on high-intensity battlefields.
Although North Korea's weapons are old, it has achieved independent production in the entire chain, has sufficient ammunition reserves, and is able to operate continuously. Compared with South Korea, North Korea's replacement is slow, but it avoids the risk of external disruption.
South Korea used to rely on the U.S. market exports of K-9 cannons, now pushing the proportion of localization from 10% to 20%, progress is in the accumulation of cost of fire control software, but advancing the development takes years, core engines still need to be imported.
The U.K. Navy has been in a recession from the day to the day, with about 50 surface ships, including a handful of aircraft carriers, totaling less than South Korea by 2025.Defense budget $57.7 billion to purchase the digital transformation supported by Google Cloud, but intelligence sharing still binds the U.S. Five Eyes Alliance.
Once the U.S. falls, it will be difficult for Britain to maintain global deployment, and North Atlantic defense will be the focus.In the past, Britain has expanded its influence in the Indo-Pacific through the AUKUS Alliance, and now increases spending to drive ship contracts, but is less large compared to 331 vessels in South Korea.
The upgrades depend on U.S. technology transfer, and domestic shipyard production capacity is limited and cannot be rapidly expanded. Poland and Ukraine's military expansion is similarly dependent, and Britain's island state positioning will force its strategic ambitions to shrink.
Poland plans to form Europe’s largest army, with an army size of 300,000 by 2025 and defence spending of 4.7% of GDP, but relying on US $400 million in loans and 8,200 troops to purchase hundreds of F-35 and rifle missiles. These high-precision missiles, previously supported by the United States to boost eastern front-end defence, are now driving domestic expansion, but training and maintenance require American experts.
Once aid is interrupted, Poland needs to reduce its confrontational stance towards Russia and seek coordination within the EU. Different from before, it has shifted from relying on the US military to multilateral cooperation, but the pressure on the eastern border has increased. Ukraine received US $66.9 billion in military aid from the United States, totaling US $175 billion for local maintenance and weapons production.
In 2025, aid freezing affected front-line supplies, and eastern stability was damaged.In the past, reliance on aid to raise firepower now shifted toward Russian economic integration, which could reshape the alliance pattern.
The conflict in Ukraine exposed the limits of U.S. aid, with European aid totalling €11.46 billion by 2025, but the U.S. remains dominant. The Ukrainian military blocked Russia’s advance through U.S. weapons such as targeted missiles, but domestic production advances slowly and ammunition consumption is high.
Once the U.S. is in recession, Ukraine may be forced to negotiate and return to the Russian track. This shift stems from close economic ties, past independence policies relying on Western funds and now influence sovereign decision-making. Russiains balance through energy exports and strengthens multilateral cooperation with Iran and China in joint military exercises.
Russia does not want the complete decline of the United States, because the United States restricts the military expansion of Turkey, Japan and Germany. By 2025, Russia will face sanctions, but its energy exports are stable, and it regards the United States as a stabilizing factor in Europe. If Turkey revives the Pan-Turkic Alliance, it will pose a greater threat to Russia's interests in Central Asia. Germany and France have strong potential military strength, and once armed, they will challenge the Russian border.
In the past, Russia benefited indirectly through the existence of NATO. Now it promotes multipolarization, but it does not want the United States to fall and upset the balance. Cooperative military exercises with China show progress, shifting from bilateral to multilateral, but the presence of the United States ensures that Europe is not unified against Russia.
The U.S. recession will reshape the distribution of power. Israel faces the siege, Japan's South Korean military strength decreases, British influence weakens, Poland panics, and Ukraine returns to the alliance. Russia benefits from the recovery of balance but does not want to completely disbalance. China, as an emerging force, strengthens its global role through economic ties, promotes mutual benefit and win-win, avoiding uncertainty brought by unilateral hegemony.
