Just in time for Trump to do the rug pull he agreed with Putin back in 2018, when they met in Helsinki and Trump took care to even destroy translator’s notes. If he wins the election, NATO is toast and Putin has carte blanche over East Europe.
Reagan was the last defender of Europe (you can like him or not, having grown up in a left political climate in the 70s of Germany, I didn't), and Reforger '93 was the last time the US seriously considered defending Western Europe. It's clear that at least from Clinton on, the defense of Europe as a necessity for balancing world power was no longer on the table, "It's the economy, stupid!".
Putin will create a crisis in the baltics and invade Poland over the Suwałki Gap, gets his ass kicked, troops getting stuck, there will be negotiations and that's that. Putin couldn't get weak Ukraine (Crimea was a coup) - Russia has 3.5x times the people and 100x the money - it's funny how people in the West still believe in the Soviet Union and the Red Army, against all evidence. The best troops of the Warsaw Pact were East Germanys NVA, and losing that and all other satelite states like Poland, there is no more Red Army.
