I think this is beyond a point of no return.
I am angry, really really angry, that we "the west" are standing by and watching Russia slaughter and destroy Ukraine. This is the first mistake of the "the west". Nevermind the sanctions, and "Putin must fail" mantra. It's absolutely not even a grain of relevance to the people being bombed, killed and displaced. It also punishes ordinary Russian people who let's face it, are controlled, so they are doubley punished.
The Second World War had already begun in Europe before Germany invaded Poland. That was the trigger to declare war on Germany
but the US didn't come in until after Pearl Harbour.
Snapshot from Wiki:
"In Europe, Germany and Italy were becoming more aggressive. In March 1938, Germany
annexed Austria, again provoking
little response from other European powers.
[52] Encouraged, Hitler began pressing German claims on the
Sudetenland, an area of
Czechoslovakia with a predominantly
ethnic German population."
