And what, exactly, was April Glaspie guilty of?
It's that in July 1990 she failed to war Saddam Hussein in strong enough language that if he invaded Kuwait, it would mean the death of him and his regime, along with eventual subservience of Suni Iraq to Shiite Iran.
Glaspie herself claims that she did warn Saddam, though in diplomatically nice language since, "We foolishly did not realize he [Saddam] was stupid.".
I don't think Vlad the Invader is stupid, but rather is acting according to his plans and calculations regarding the weakness of Ukraine and the West generally, the USA's leadership specifically.
