This is how you create terrorists.
What do you think the children and friends feelings towards the US will be from now on?
People get radicalized for much less than that.
Comparing the reactions between this (seemlingly little) reported incident, and the attack on Saudi oil facilites (zero fatalities) is an interesting exercise.
Yeh the difference in the press' reactions between the two is pretty stark. However the most interesting thing about the Saudi attack is the faux outrage at the idea that _Iranian_ arms were used in the attack. As if it's totally cool that British and American arms are used by the Saudis to flatten Yemen but the idea that the Houthis can strike back with Iranian-provided arms is somehow a despicable disgrace.
