The Summer War in Gaza Is About to Begin

As the temperatures climb in Israel and Gaza, it's not just the air that's heating up. The Palestinians can't seem to decide whether they want to kill each other or kill Israelis, and the Israelis are starting to aggressively take out Hamas strongholds. Everything is setting up for another war:

An Israeli airstrike destroyed a Hamas compound in central Gaza City on Thursday, killing one and wounding at least 45 people, Palestinian witnesses and medical officials said.

The strike came a day after 22 Palestinians were killed across Gaza City in the most widespread factional fighting in nearly a year between Hamas and Fatah. The raging street battles have turned the densely populated seaside city into a war zone, putting terrified civilians increasingly at risk.

The army confirmed it carried out the airstrike, which came after Israel threatened "harsh" action in response to repeated Palestinian rocket attacks.

The explosion sent heavy plumes of smoke into the Gaza sky, completely destroying the structure and several others around it and sending terrified residents scurrying.

Hamas said the target was an administration building of its elite bodyguards unit. The two-story structure is normally filled with Hamas personnel.

If they get going in the south again, what will happen with Hezbollah? Will they join in and turn the entire region into a war zone? They're feeling pretty cocky after last year's war and I'm sure by now they've re-armed and re-supplied. Given the anemic response by Israel last year, why wouldn't they get involved?
