With every strike and counterstrike, Israel, the US and Iran's allies inch closer to all-out war

In the last week alone, Israel has killed a senior Hamas militant in an airstrike in Beirut, Hezbollah has fired barrages of rockets into Israel, the U.S. has killed a militia commander in Baghdad and Iran-backed rebels in Yemen have traded fire with the American Navy.

Each strike and counterstrike increases the risk of the already catastrophic war in Gaza spilling across the region. And in the decades-old standoff pitting the U.S. and Israel against Iran and allied militant groups, any one party could choose all-out war over a loss of face.

The divisions within each camp add another layer of volatility: Hamas might have hoped its Oct. 7 attack would drag its allies into a wider war
