Israel launched a wave of strikes across Iran on Friday that targeted its nuclear program and military sites, killing at least two top military officers and raising the prospect of an all-out war between the two bitter Middle East adversaries. It appeared to be the most significant attack Iran has faced since its 1980s war with Iraq.

The Global Firepower index (GFP) grades the strength and capabilities of every military in the world. Until recently, Iran was higher than Israel on the index, dropping to number 16, while Israel climbed to 15, out of 145 respectively. For perspective, the US, Russia and China are the top three.
