If this is the same guy we're speaking about, he later admitted to not being given the full facts, jumping to conclusions and removed the tweet as he didn't wish to misinform.
Sound familiar? It also does not address the fact that: the rocket was NOT Israeli. NOT fired by Israel. NOT intended to hit the al Alhi Arab Hospital and didn't hit the hospital at all. It's not the gotcha you think it is and doesn't do anything to absolve Islamic Jihad's suspicions of being responsible either. Again, you are basing your entire justification on a TWEET.
You REALLY want Israel to have been responsible for this, don't you.
