Louisiana Gov. Bobby Jindal said that Kentucky Sen. Rand Paul was “unsuited” to become the U.S. president. Jindal slammed Paul for his remark that the rise of the Islamic State group -- also known as ISIS or ISIL -- was due in part to “the hawks” in the Republican Party.

"This is a perfect example of why Sen. Paul is unsuited to be commander-in-chief,” NBC News quoted Jindal as saying. “We have men and women in the military who are in the field trying to fight ISIS right now, and Sen. Paul is taking the weakest, most liberal Democrat position."

Paul has already declared himself a candidate for the Republican Party's 2016 presidential nomination. Jindal has yet to announce whether or not he will run.

Jindal’s comments came after Paul said Wednesday that foreign policy hawks in the GOP had made mistakes for decades. While Paul was earlier supportive of the U.S. forces taking on militant powers all over the world, he later started criticizing U.S. involvement in overseas issues. Paul's political rivals immediately started labeling him an isolationist.

Paul has long claimed to be a "different type" of Republican. For example, he has said that Republicans had mistakenly positioned the party as anti-environment. CNN reported that the “crunchy conservative” said that he was a “tree hugger” and was “proud of it.” Paul added that the Republican Party had a “broken” image. For instance, he said that the party was scaring away minority voters instead of trying to attract them.

Jindal criticized Paul’s approach on foreign policy as “outlandish.” The Washington Post reported that Jindal suggested indirectly that Paul's views aligned with those of President Barack Obama and former Secretary of State Hillary Clinton, the front-runner for the Democratic Party's 2016 presidential nomination.  

Jindal said that it was people like Obama and Clinton who were more responsible for the rise of ISIS. He said that it was clear that the reason behind the rise of the extremist forces was radical Islam.

Paul has often expressed disagreements with his own party members on foreign policy issues. He has had open arguments with major politicians like Sens. Lindsey Graham and John McCain over military issues.
