We haven't established that Omar was criticizing Israel for defending itself.
That tweet was written in 2012 the context of Israel defending itself from aggression from Gaza (thousands of artillery rockets being shot at Israeli towns and cities).
It has no qualification, so natural reading of the tweet is that he objects to Israel defending itself.
Again, the tweet:
I suspect she was criticizing Israel for killing unarmed civilians but we'll have to wait for Derec to provide the context.
There is no indication that that's what she meant specifically.
And it is inevitable to have some collateral damage in any war. Especially when one side (Hamas) loves to use civilians as human shields.
So she made that tweet during
Operation Pillar of Defense, and a day after intense Israeli tank, artillery, and missile fire into Gaza that imperiled the lives of hundreds of thousands of civilians.
You don't think it's possible she was responding to the humanitarian crisis in Gaza and the lack of concern shown by the powers-that-be in Washington? You think her motive for tweeting a prayer people would awaken and see the evil doings of Israel could only be hatred of Jews? I think you're wrong.
I think that as someone with first hand experience of war, who knows what it means to be hiding in your home and praying no one decides to blow it up, she has some pretty strong opinions on this issue. She's probably the last person in Washington who would approve of a missile strike into Gaza
or Tel Aviv, no matter who was the target.
She also knows just how much the destitute and refugees in camps need donated aid. I doubt she will ever look favorably on those who would withhold it for political reasons.
I wonder, do you think Palestinians have a right to defend themselves? You noted that Operation Pillar of Defense was in response to thousands of artillery rockets being shot at Israeli towns and cities, but don't note that the rocket fire was in response to
Operation Returning Echo, an Israeli strike that killed a Hamas leader which broke the 2011 ceasefire. Of course there was a reason for Operation Returning Echo. It was retaliation for pre-ceasefire cross border raids which were a response to the blockade which was a response to Hamas gaining control of Gaza, etc., etc.
The point is, the fighting is mutual. As you say, it's war. If Israel has a right to drop explosives on Gaza, surely the Gazans have a right to do the same to Israel. Not that Rep. Omar would approve of civilians being targeted in either case.
