Israel invades the gaza strip.

They didn't kick anyone.
Like I said a few posts ago, the Arabs who chose to stay in 1948 were not massacred, deported, robbed, subjugated, or otherwise abused. They were given full citizenship and equal rights. Still have those rights, them and their descendants. They make up about 20% of Israel's population.
The ones that ran away, did it on their own initiative.

Unfortunately, sources are way too damm conflicting on this. Jews say the Arabs ran away (or...stayed) and the Arabs say they got kicked out. Heck, probably both happened. The ones that did run away, though, expected to come back. They didn't. So for all intents and purposes, they got kicked out.
