Hamas interior minister Fathi Hammad accused Israel of planning to invade Gaza, and since imaginary threats are so thoroughly offensive, he decided to make a real one in response (a "cycle of threatened violence," if you will.)
Speaking at a university in Khan Younis, Hammad said that Hamas, accompanied with the armies of the world, will come to Haifa and Acre to liberate them from Zionist control.
He bragged that Israel is spending so much effort on missile defense, saying that the "occupation" is hiding behind walls and Israelis are unaware that they are trapped.
Moreover, he said that the siege of Gaza has made Gazans stronger and more steadfast.
