You bring up an interesting dynamic: War involving Iran, Afghanistan, and Pakistan. The former is shia, and the latter two are sunni (though both have minority shia populations). Iran is pissing off a lot of people lately; perhaps it is on the verge of building its first nuclear weapon, and is feeling its oats. Or, perhaps it is just being Iran, the bothersome and annoying kid on the block who gets along with no one.
“Iran, the bothersome and annoying kid on the block who gets along with no one.”
And that includes not getting along with it’s own people. I wonder how the unhappy restive population will react if a more serious situation develops with regard to the mutual strikes with Pakistan. News tonight reported civilians including children were killed by both the attack in Pakistan and the reprisal in Iran. The news comment said these were serious enough strikes to make further actions likely.
