Why did God allow the 9/11 attacks to occur?

An omniscient God would've known the attacks were coming. A beneficent God would've wanted to prevent the attacks. An omnipotent God could've stopped the attacks with ease. If these things are not true of God, then He is not worthy of worship. So either God doesn't exist or He simply hates America. (Thanks to Epicurus)

He didn't, God doesn't exist.God hates America.
