Conflicts are always terrible, and the Eurasia / Africa region countries are particularly brutal.
Every citizen of every country has a human right (in a civilized civilization / society) to live a life that does not involve violence. A life where they are not worried about RPGs, bombings, (etc,) or military invasions.
Some sources of conflict involve places which various (different) religions hold as sacred / holy. Those sites should become UN world heritage locations and be managed by the UN in ways that only allow non-military peaceful access for any who want to visit.
With respect to Gaza my personal opinion remains unchanged. Both an innocent civilian people who suffer, and a terrorist government, remain in that region. The civilians should be evacuated. The terrorists who remain after (or whom are caught and found guilty in a trial) should be purged. The country should then be cleaned up, rebuilt, and returned to the innocent people along with a training-wheels UN supported government that brings stability, peace, and prevents a resurgence of hate and terrorism. In a few generations the country can grow more stable and graduate from the guided government structure.
That would be not just a two state solution, but a two states and global peace sites solution.
