So are you saying we should have let Hitler do his thing because we didn't stop the crusades and to avoid appearing "woke"
Your entire argument completely ignores the fact that as a species we learn and our perception of right and wrong changes with experience, there is no doubt that our responses to certain events is also largely driven by political expediency but for the most part as the "people" gain more of a voice they tend to be opposed to wars for any reason.
But once again what my country or anyone else country did in the last 100 to 5000 years does not make the Russian invasion of Ukraine any more acceptable so we have picked a side now it's time to see how that plays out (doesn't sound all that "woke" to me).
Perception of right or wrong has no place in international politics,because this perception leads inevitably to WW3 and the end of mankind .
There are two different reasons for intervening in a war
1 A attacks B and if A wins,it is a threat for our interests .This is the policy intelligent people are following .
B Moral reasons :a war of A against B is bad because A is a dictatorship ,if you follow this argument, you must intervene in all conflicts on earth which will result in the end of the world and you can't do as A ,you can not invade an other country ,countries as Afghanistan or Iraq .
Britain intervened justifiably in August 1914 when Germany attacked France and Belgium,because this attack threatened Britain's interests,but it remained neutral when Germany attacked Russia,because this attack did not threaten British interests .
The British DOW on Germany because Germany attacked Poland was stupid and suicidal,as the existence of an independent Polish state was not essential to protect British interests .
When Japan invaded China in 1931 and murdered millions of Chinese both US and Britain remained neutral and US did sell Japan the needed war material to kill millions of Chinese .
When the Soviets intervened in Afghanistan, stupid Carter imposed sanctions on the USSR and lost the elections . His successor, Reagan,stopped these sanctions and sold the Soviets again grain .Because ? Because the farmers from Kansas and Nebraska, GOP voters would otherwise lose a lot of money .
Thus from a moral POV there was no need to declare war on Germany in September 1939 .
When Hitler invaded CZ in March 1939 ,there was no British DOW, thus why was there any need for such a DOW in September 1939 ?
The chief responsible was Woodrow Wilson, the American Trotzky, who poisoned the souls of the peoples of Europe by lying that the aim of US participation in WW! was to make the world save for (US liberal ) democracy .
And it is a fact that Wilson openly defended the Jim Crow laws .
