Your comment deflects to reasons for the war. It does not address the core argument that it really wasn't a peace deal and that Russia commonly violates ceasefires. What good is a ceasefire when you know that Russia will violate it?
Doesn't sound like a deal (good or bad) at all. It's a paper prop for Trump to wave around and exchange for a gold star from Putin.
As far as the US and allies are concerned, this is very simply a war for the protection of Ukraine's sovereignty. Now that the US changed into a wannabe imperialistic nation, the picture is not so clear.
Whoever thinks that Russia will ever consider the US as an ally probably doesn't have a great sense of how Russia views itself and the US.
They'll play the part of ally, to a limited degree, when their stooges in Western Democracies don't have any demands of them. But no amount of trade will change their priorities as far as diminishing the dollar with something they at least partially control.
