What are the concerns about US troop withdrawal from Europe under President Trump?

There's growing concern that President Trump may scale back or entirely withdraw American troops from Europe, particularly from the Baltics where approximately 5,000 US soldiers are stationed. This potential withdrawal has sent shockwaves across the continent, with European officials viewing it as a major security risk. In total, there are about 100,000 American troops in Europe, alongside approximately 100 B61 nuclear gravity bombs deployed at six NATO bases across five European countries. The implications of a US withdrawal would be severe: a potentially weaker NATO alliance, an emboldened Russia, and deepening divisions within the European Union over how to respond to these security challenges.
