I still remember when one of the concessions (only concession at the time?) was "we'll stop calling you terrorists", as though Yemen was desperate to suck up to fickle Western opinions. I still remember when I saw a video of a Yemeni farmer who went to the states to beg congress to stop selling bombs to Saudi Arabia, recounting the horrors they faced when death could drop on them at any time with zero warning because they'd never see the jet above them, their children frightened of death coming without warning.
Our government can't be reasoned with, if you make the mistake of thinking you're dealing with human beings it'll be your funeral.
