Trump's GOP opponents bristle at his response to Hamas' assault on Israel

Republican presidential hopefuls are rebuffing former President Donald Trump after he declared Hezbollah "very smart" and criticized Israeli Prime Minister Benjamin Netanyahu days after Hamas' massacre of Israelis over the weekend. 

Florida Gov. Ron DeSantis, former Vice President Mike Pence, former New Jersey Gov. Chris Christie and former South Carolina Gov. Nikki Haley condemned the GOP presidential frontrunner's comments, after Trump's remarks on the crisis. 

At a political rally on Wednesday, Trump said Netanyahu "let us down" before the U.S. killed top Iranian military commander Qassem Soleimani in 2020, and said Israeli leaders need to "step up their game."
