What was the use of the US fighting the Cold War with the USSR now that America seems fine with embracing Putin?

Don’t see Americans marching and protesting at the WH re the issue. And all the things Trump is doing supposedly against Putin seems superficial and just a ploy to make it look like he’s doing something. Putin would have made serious threats and follow through if he is genuinely pissed imo.

America did support dictators before so in the case of Putin, are the issues similar?
