I'm genuinely curious: Which brutal dictators are currently receiving U.S. arms? With Mubarak gone I can't come up with any. The Saudis? Hard to describe what they're running (or at least barely managing) as a dictatorship.
Pakistan? Their democracy is a joke. The military holds all the power as evidenced by the multiple military coups in their past
Knowing nothing about Pakistan, don't the coups demonstrate the lack of power military holds? If I was a military chief, I'd rather prefer to steer policy from the background assuming I had any real influence. Not saying you're wrong. I'm trying to understand...
They depose a leader then to retain US support they allow elections then depose him when they no longer approve. Might as well be a Itanian style theocracy.
Army chief el-sisi, who deposed the last elected leader is now the new "elected" leader. When it comes to words like "iron fisted" "tyrannical" "repressive" el-Sisi makes Mubarak like your friendly mailman. But Obama supports him, so I guess that doesn't matter for most people (not speaking for you).
