GOP's Bob Corker: Obama foreign policy 'hard to watch'

President Obama “cannot be counted on” by people around the world looking for support, according to the senior Republican on the Senate Foreign Relations Committee.

In a searing op-ed published Wednesday in The Washington Post, Bob CorkerRobert (Bob) Phillips CorkerKorean peace talks pose new challenge for Trump GOP senator: Democratic opposition to Pompeo 'driven 100 percent by politics' Corker: Charming North Korea into getting rid of nuclear weapons is not realistic MORE writes that Obama’s policy has been “hard to watch” both for people in the United States and allies looking for support from tyranny and terrorism.

“Those around the world who are looking to the United States for support against intimidation, oppression or outright massacres have learned a tough lesson in the past few years: This U.S. president, despite his bold pronouncements and moral posturing, cannot be counted on,” Corker wrote.

The Republican blasted Obama’s response in Syria, Libya and Ukraine.

In Syria, he said the administration openly encouraged opposition groups to campaign against President Bashar Assad’s regime, but failed to provide lethal assistance.

“The president encouraged the opposition to swallow deadly risks, then left them mostly hanging,” he said. 

In Libya, Corker faulted Obama for not doing enough to mediate tribal disputes after Libyan leader Moammar Gadhafi was overthrown. He said that failure had “spurred violent chaos and destroyed what was left of Libya's social order.” 

Corker called his response to Russian aggression in Ukraine “tepid.”

The White House has been hit with a series of foreign policy crises that have challenged the administration and eaten into his poll numbers.

Corker's criticism comes a day after a Wall Street Journal-NBC poll was released that showed the president with record-high disapproval ratings on his handling of foreign policy. 

Sixty-eight percent disapprove of Obama's job on foreign policy, and 36 percent approve, according to The Wall Street Journal

The president defended his foreign policy earlier this year, saying it “avoids errors.”

“You hit singles, you hit doubles; every once in a while, we may be able to hit a home run. But we steadily advance the interests of the American people and our partnership around the world,” Obama said on April 28. 

Corker mocked that characterization. 

“More often than not, the president doesn't hit singles and doubles; he just balks,” he said.
