Not sure why you claim this as fake news, NATO website confirmed deploying battalions for “exercise” in Romania, NYP confirms the documents with the secret plans for 800k troops are accurate, in response Putin is mobilizing 1.5M. Biden did this in response to both Putin and Trump publicly stating they are willing to negotiate an immediate cease fire if Ukraine wants to come to the table after they lost 40% of the area they had captured this summer.
If you want to know how they plan to get 800k (let’s be honest, US) troops, Biden made an executive order in 2021 to make sure the DoD has the capacity that “all Americans who are qualified to serve in the Armed Forces of the United States should be able to serve” - aka instituting a draft if necessary under the guise of trans rights.
Biden got nearly 3 months before Trump has any official capacity, he is under the misguided idea from mainstream media that Russia is weak and can be completely defeated, it would be, if it were possible, his only legacy after a failed career, failed presidency, one disputed and one failed candidacies, failed Afghanistan pullback. And I don’t doubt for an instance, the US can win in less than 30 days and take all the land between Kyiv and Moscow, but it would be an expensive, bloody and nuclear war, the Normandy landings would pale in comparison, but Biden, as we saw from Afghanistan cares nothing about the people he needs to run roughshod over to try and get a political legacy win.
