As reprehensible as Terry's death is, we should not lose sight of the fact that these weapons were provided to violent criminals who killed Mexican citizens, and without Mexico's knowledge. In addition to the sheer crime of the loss of lives, that is dangerously close to being an act of war against a (nominally) friendly foreign country.
Is this what Obama fears?
I’d say this was bordering on, if not completely stepping over the line of,
an act of war.
Now, it would be considered that, UNLESS, the Mexican government was in on it as well as a co-conspirator. In which case, they are just as evil if not more so - sacrificing their own citizens and law enforcement on the altar of gun control and Marxism.
