Almost Every Arab country pretty much did attack Israel and an estimated 24 Arabs died approximately for every Israeli that died. They even had modern tanks and weapons from Russia. Israel totally owned on the battlefield.
But what if there was a global Jihad where every single Islamic-majority country declared war on tiny Israel, do you think Israel would still stand their ground?
It would attempt to hold it's ground while unleashing weapons and tactics not covered by the rules of war as religious warfare is not covered by rules of war. Tactics seen in Gaza and the WB would just be the tip of the "iceberg". The least I expect is forced displacement in Israeli and held territory (Gaza and WB are technical part of the Israeli government). Deployment of mine fields as per the Lebanon/Israel War. Massive destruction of property due to military action for both offense and defense. For example I could see clearance of buildings to establish a useful field of fire, 2 miles or more.
That's really a tiny strip of land theyre fighting over. I think Israel would still win.
I think religious fanaticism would make a war of attrition more likely than the previous national battle cry. The numbers are not in the IDF's favor. I think Israel would lose such a war in the long run.
I think such a war would follow a Clausewitz derived strategy such as Total War (not the game). Civilian are bombed, cities are targets, etc. Sherman, Grant, WW2 Western air warfare, Eastern Front.
*I think such a conflict would trigger a World War. I do not see the US standing by watching a global Jihad engulf a large part of the planet. China and Russia would at least use it as a pretext to purge or contain it's ethnic populations which are Muslim. The EU will write serious letters*
*I take your scenario as is without injection of current geopolitics. It is Israeli vs a unified Jihad.*
