See people always say this, but it isn't some universal truth. Often people get exhausted and would prefer a shaky peace with a compromise over writing about random bombs and rockets.
The IRA and Ireland (I've often seen people comparing Hamas to the IRA situation, but just imagine if the IRA had been demanding not only a united Ireland, but they also wanted England, Scotland, and Wales too). ETA and basque country. Although there are a lot more extremist groups in that region that could take hold, I will admit. Which is why Israel is likely planning on a wider more strict dmz until peace can be agreed upon and sustained. And if it cannot, then Gaza should probably work on their Egyptian diplomatic relations and a 3 state solution is more likely here.
Because even if you want to think bad things about Israel's government, they are working hard on diplomacy in the region and do not want repeated war with Gaza to sidetrack it. They were supposed to have diplomatic talks with Saudi Arabia until Hamas attacked them. Already have them with several Arab league nations. A large dmz, Hamas removed from power, and Gaza being forced to work with Egypt might accomplish that.
Do you often like to toss out obvious statements that no one was debating into conversations?
