How might a potential US troop withdrawal from Europe impact NATO and European security?

A potential US troop withdrawal from Europe could severely weaken NATO and create significant security risks. Currently, about 100,000 American troops are stationed in Europe, including 5,000 in the Baltic states, along with approximately 100 B61 nuclear gravity bombs at six NATO bases across five European countries. The withdrawal would likely embolden Russia while creating deepening rifts within the European Union over appropriate responses. European officials view this possibility with alarm, as President Trump's willingness to consider withdrawing troops from Estonia, Latvia, and Lithuania has already sent shockwaves across the continent. The implications are stark: a weaker NATO alliance, increased Russian aggression, and a divided Europe struggling to formulate a unified defense strategy.
