Im sure the likes of CXRAndy have full of stiffy's with what his orange gibbon messiah and his brinkmanship has done over the last month, but there will be a price to pay. Any US president over the last 80 years could have done this but they didn't, recognising the wide ranging benefits for the US with having strong influence in Europe, Not all of it good, but never bad for US industry and it's economy.
Putting NATO completely at risk, that will disrupt the security of Europe, for what can only ever be token increases in defence budgets, compared to the US is nothing more than right wing theatre. Poland spends nearly 5% of its budget on defence, which is more than the US at 3.4%, and yet Polands entire fast attack aircraft could sit comfortably, with plenty of room to spare on one of the US Navy Nimitz class aircraft carriers and they have 10 of them.
There is far more to simply X amount spent on defence as a percentage of GDP that the orange alien is demanding. Industry, Economics, Social and cultural differences to name a few and only the thick grunts who are way out of their depth intellectually on anything unless it's changing the bog roll, are cheering him on, because somehow, it is sticking it to wokeism and the EU... Like i said, there will be a price to pay, far beyond a simple half a percentage increase in spending on defence here and there which is like a piss in a bath in the grand scale, but real extistential threat to the entire continent and as far as the US is concerned, real irreversible damage to it's own economy, society and standing as a result.
