It is probably because many disagree with you.. most countries want to be in NATO more than ever to group up against the Russian threat… highly doubt one would leave..on balance more will try to join than leave.
Russia is weakened and has lost support from previously neutral countries.
The US doesn’t need to fight Russia and China. Straw man argument… since that scenario is highly unlikely. In any case, it’s US & NATO allies versus who ever… the Chinese want to make money and become economically dominant…which doesn’t align well with war when you want to trade…
Your view is so upside down…I almost believe you are a Russian troll
