US President Barack Obama has made powerful Washington’s enemies China and Russia during his term in the White House, says Republican presidential candidate Rick Santorum.

“Every step of the way, he has been soft on our enemies and harsh on our allies,” Santorum said on Saturday.

“He has empowered China, he has empowered Russia, he has empowered ISIS (ISIL) and he has empowered Iran,” he added.

Obama's critics believe that he was not dealing with superpowers properly.

They also say the president’s strategy regarding the ISIL terrorist organization has been a failure.

Obama ordered airstrikes against ISIL targets in Iraq and Syria one year ago. However, the group now controls many regions in the two Middle Eastern countries.

The terror network is killing hundreds of innocent civilians and spreading fear among people by their brutal and disgusting crimes.

The 2016 presidential hopeful also said he would destroy ISIL if elected as president.

“We have not taken this threat seriously,” Santorum said. “We must take back their land and we must destroy their state.”

“If I am elected president, we will defeat ISIS (ISIL),” he continued. “I will make sure ISIS (ISIL) is not spending their money on weapons – I’ll make sure they’re spending their money on body bags.”

Republicans are targeting Obama’s foreign policy record one year before the 2016 election.

Other candidates, former Florida governor Jeb Bush, Senator Rand Paul, Senator Marco Rubio, former Arkansas governor Mike Huckabee, and billionaire Donald Trump have slammed the US president so far.
