Picking and choosing who one "intervenes" with and who one leaves to their own devices.........sounds like abuse of power and politics.
Of course the US does not choose "randomly". Iraq was DELIBERATE. PREMEDITADED. and ILLEGAL.......and only a select few were involved in the planning discussions. The select few being in favor of course.......or had been skillfully manipulated by the bush goons.
Of course there are "discussions". But the motivation and thrust is by the most war loving nation on the planet. Deciding who to bomb / ie kill, slaughter, maim and otherwise ruin for life must give the "deciders" such a god like feeling of power ..
By the way, my reply was about Yemen, but as long as you mentioned Iraq. What is this ILLEGAL you mention, who's laws were broken Iraq's? Saddam was totally disobeying U.N. mandates, no fly zone and the U.N. chose to let him do it. We didn't, so what. As to war loving, read more history.
