European armies can barely generate one combat-capable brigade (3,000-5,000 troops) despite the presence of perhaps 250 brigades in Ukraine, demonstrating severe European military under-capacity relative to conflict requirements.

NATO war plans indicate that to fight credibly, European forces would need to spend above 3% of GDP on defense, with NATO Secretary General sometimes using the figure of 3.7%, accounting for the loss of some American capabilities if America shifts focus to Asia.

American tactical nuclear weapons (B61 gravity bombs) are deployed around Europe and practiced by European air forces (German, Belgian), and if the American nuclear umbrella is withdrawn, Europe faces a strategic problem because British and French nuclear arsenals are very small and Britain's deterrent is partially dependent on American support, while France's isn't formally devoted to NATO.

Europe is beginning to show real sense of urgency about addressing military vulnerabilities, with emergency summits in Paris, London, and other locations discussing defense spending and structural dependency reduction.

Beyond the financial challenge of paying 1-3 additional percentage points of GDP for defense, the real difficulty is translating cash into actual military capability, including manpower recruitment and training.

Any European military deployment in Ukraine would require very significant American support with enablers—intelligence, airlift, sea lift, logistics, headquarters, command-and-control for air operations—that Europe cannot generate independently and that fundamentally creates exceptionally high dependency on America.

European military weakness stems from the 1990s and afterwards when European countries cut defense spending massively and hollowed out their forces after the Cold War ended, reversing the earlier period when Europe had big, flourishing armies with adequate ammunition stocks and training.

The UK just announced it will spend 2.5% of GDP on defense by 2027, which is the biggest sustained growth in spending since the Cold War after 20 years of stagnant defense spending.

Any European military deployment in Ukraine would require very significant American support through military 'enablers'—intelligence assets, airlift, sealift, logistics, command and control infrastructure—capabilities that fundamentally cannot be rapidly developed or purchased off-the-shelf.

European armies underwent a massive force reduction following the Cold War in the 1990s when they cut defense spending dramatically and hollowed out their forces, creating structural deficits that persist decades later and cannot be rapidly reversed.

NATO war plans consensus indicates Europe would need to spend above 3% of GDP on defense (with some estimates at 3.7%) to credibly fight with current NATO forces, a figure well above existing spending levels.

The Dutch Armed Forces are approximately 49,000 personnel, less than one-fifth the size they were during the Cold War, with about 1 in 10 positions unfilled and 2023 enlistment yield of 3,600 soldiers against a requirement of 5,000.

Most European armies cannot generate even one combat-capable brigade, which consists of 3,000-5,000 troops, while Ukraine has approximately 250 brigades across all sides, highlighting the severe force-generation gap European NATO members face.

The British Armed Forces announced spending of 2.5% of GDP by 2027, representing the biggest sustained growth in defense spending since the Cold War and the first such increase in 20 years.

Translating increased defense spending into actual military capability is difficult independent of the financial cost because structural obstacles exist: recruitment shortfalls, manpower gaps, and inability to rapidly develop complex command and control systems.

America deploys tactical nuclear weapons (B61 gravity bombs) around Europe, which European air forces including German and Belgian forces practice carrying, providing protection against nuclear-armed adversaries like Russia.

German chancellor Friedrich Merz publicly raised the question of whether Germany must now discuss compensation for loss of American nuclear shield with Britain and France, Europe's two nuclear-armed powers.

European leaders are meeting in emergency and regular summits in Paris (recently held), London (scheduled for Sunday), and days after, discussing defense spending increases, changes to European Union fiscal rules to allow higher spending, and potential seizure of frozen Russian sovereign assets to fund Ukraine and free up money for European armies.

European defense strategy should focus on identifying which areas create maximum American dependency and specifically targeting those gaps so that in a future conflict when America says 'I'm out,' Europe doesn't have to call Washington for critical capabilities.

The nuclear question is a real problem that Europe will have to confront this year, potentially requiring France to formally devote its arsenal to NATO and changes in European nuclear arrangements.
