The problem is that stopping support now after US congress and president had vowed to support Ukraine "for as long as it takes" is going to be far more expensive. Small things like Tesla sales crumbling, which means less tax revenue. The US had 320B USD in arms sales 2024. Usually about 60% of that stays in country as tax revenue. Europe is upping its spending massively but a big part is developing production capacity for the most complex and expensive stuff that will be in direct competition to the US. Never mind such BS like the US vetoing Grippen to sell their planes to Colombia because of the use of US engines. All in all the US has proven itself to be an unreliable ally. This lack of trust will result in additional costs and lost opportunities in the next decades.
