<tongueincheek> I can't understand why rulers in the Middle East can't understand the thinking of our Presidents, which seems to me to be entirely logical and eminently comprehensible to anyone. First Saddam Hussein thought he could bluff his regional enemies by pretending to have chemical weapons without affecting Pres. Bush's thinking. Now Assad thinks he can intimidate his rebellious subject by using chemical weapons without affect Pres. Trumps thinking [sic]. </tongueincheek>
Seriously, it's always good to remember that other people don't understand you as well as you do, which assumes you understand yourself, which can be an erroneous assumption.
