Germany didn't attack England

England attacked Germany.

Germany counterattacked England.

And England attacked Germany
supposedly 'in defence of Poland',
or, actually, in order to continue propping up
some infamous 'Piłsudski's colonels' hunta regime,
which no-one seems to mention somehow.

Now, once Germany (and most of Europe) were destroyed by WWII,
the Polish people were promptly delivered to Stalin,
the main 'good guy' of WWII, and,
incidentally, the worst mass murderer of the 20th century,
you know the one that did e.g. this:

The Katyn massacre was a series of mass executions of nearly 22,000 Polish military officers and intelligentsia prisoners of war carried out by the Soviet Union, specifically the NKVD ("People's Commissariat for Internal Affairs", the Soviet secret police) in April and May 1940. Though the killings also occurred in the Kalinin and Kharkiv prisons and elsewhere, the massacre is named after the Katyn forest, where some of the mass graves were first discovered by German Nazi forces. The order to execute captive members of the Polish officer corps was secretly issued by the Soviet Politburo led by Joseph Stalin.

WWII ended up costing ~80 million lives ...
in order to give Poland to Stalin.

Worth it, was it?
