How many people were held by Iran in US embassy seize? What could US do if they were all killed in one go? We have not witnessed such a shameful act with other countries because there have been very less number of savages. Even if US citizen were held hostages in that number, there is nothing that it could do expect threaten ISIS with it's military might. sadly, ISIS is bunch of moronic savages who seek glory by killing innocent unarmed people. Example, captured pakistani soldiers killed by talibs in pakistani soil itself.
