After President Barack Obama's prime time speech on Wednesday, Senator Rand Paul (R-Ky.) said that the U.S.' approach to foreign policy has led to more threats to the country.

Paul, a possible candidate in the 2016 presidential run, discussed Obama's strategy against Islamic State of Iraq and the Levant (ISIL) in an interview with Robert Siegel of private media firm National Public Radio (NPR).

While he believes ISIL is a threat to the American people and supports the U.S. efforts to defeat the terrorist group, the Republican senator also thinks Obama is doing things "the wrong way." He said Congress holds the authority to declare war, based on the U.S. Constitution.

The Federalists did not want the executive branch of the government to declare war without securing approval from Congress, Paul explained.

"I do support combating ISIS... I just think he's going about it in the wrong way," Paul said of the anti-ISIL strategy Obama announced.

Congress should deliberate the decision to launch military campaigns against ISIL and whether it needs to be done or not, Paul stated.

In his speech Wednesday, Obama spelled doom for anyone who threatens the U.S. However, the strikes in Libya and Syria have only strengthened the Islamist group and created a "safe haven" for them, Paul said in the interview.

In fact, the U.S. strikes against Syria has only provided a safe haven for ISIL in the last couple of years, the Kentucky senator said. Efforts to support the rebels have only opened Syria's gates to millions of dollars' worth of arms, the senator added.

Moreover, the Republican senator thinks America has "gone too far" in hopes to instill democracy in the Middle East. The U.S. has repeatedly helped kick out dictators, but those ousters have only sown chaos in the region, Paul argued.

Citing the situation in Libya, Paul said Obama's intervention to kick out a dictator has only heightened the safety concerns in the country and has made the latter more of a threat to the U.S. He said the same thing happened to Syria.

Previous interventions only brought more threats to the U.S. than there ever was. Paul suggested the U.S. should take a "more realistic" approach in its foreign policy and see if every decision contributes to the country's stability or not.
