Washington (CNN) Republican Sen. Rand Paul is criticizing President Donald Trump's actions toward Iran, saying his decision to withdraw from the Iran nuclear agreement and last week's drone strike that killed the country's top military general have made the US less safe.

Although Paul is typically dovish when it comes to military action and overseas entanglements, his comments on Iran are a break from other congressional Republicans, who have overwhelmingly backed the President as he's taken a hard-line approach toward the longtime US foe.

"The Iran agreement wasn't perfect -- and I was a critic of the Iran agreement -- however, I think it was a big mistake to pull out of the Iran agreement. We should have tried to build upon the Iran agreement," the Kentucky Republican said Tuesday in an interview on Fox News. "We've now killed one of their major generals. I think it is the death of diplomacy and I see no way to get it back started until the revenge of the Iranian people is somehow sated."

He continued: "I hate this. I hate that this is where we are going. I have been someone who has been for engagement, but there was much less killing, there was much less violence after the Iran agreement. In fact, there was a lull, a period in which I think we were headed towards a much more stable situation with Iran, and now I think that's gone. And I think it may be gone for a lifetime."

In an interview Monday with CNN's Wolf Blitzer on "The Situation Room," Paul said that "the administration, mainly at (former national security adviser) John Bolton's behest, tore up the Iran agreement, placed a significant and severe embargo on Iran and then killed one of their major generals."
