The October 7 attacks on Israel by the Palestinian terror groups Hamas and Palestinian Islamic Jihad are being compared to 9/11 and Pearl Harbor. In fact, with more than 600 Israelis dead at the time of this writing, the proportional death toll is several times higher than that of 9/11, and the factor of surprise is arguably greater than at Pearl Harbor.

But 9/11 and Pearl Harbor weren’t just tragic attacks. They were casus belli for seismic wars. Israel’s prime minister, Benjamin Netanyahu, has declared his country to be heading into “a long and grueling war.” The air attacks he ordered in Gaza have already resulted in hundreds of Palestinian casualties. Will October 7 also lead to a broader conflagration in the region? Most important, can Israel rightly consider itself to be engaged in a shadow conflict with Iran?
