But it didn't. I posted somewhere else of the terrorist deaths by Islamists, it was IIRC 250,000 in the past 50 years. Not by wars, note, but actual terrorist attacks. Palestinians have carried out a small fraction of these as a result, it can be argued, of the Gaza situation, but given their history we can be fairly sure they'd commit a lot more if they had the chance. Not just against Israel and the West but against other Muslim countries, No. 1 on their list being Jordan.
And just imagine what would happen if Palestine was a nuclear power instead of Israel. There'd be cities levelled in a dozen countries before lunchtime.
