Sen. Ted Cruz, R-Texas, criticized President Obama’s foreign policy on Fox News Monday night, asserting that the United States, under President Obama, has grown weaker.

“If there is one principle that has proved true from time and memorial, it is that bullies and tyrants don’t respect weakness,” Cruz said. “And our friends have sadly grown to learn that the United States under this president has not been a resolute ally.”

Cruz pointed out that Obama’s continued inaction on Syria was a signal to Iran that there was little to fear from the United States, and would encourage them to develop nuclear weapons.

Cruz also criticized Obama’s actions in Egypt, pointing out that protestors in the country were accusing the United States of standing with the Muslim Brotherhood government under President Morsi.

“What a sad state of affairs when the United States is arm and arm with oppressive Islamist governments,” he said.

Cruz specifically addressed the situation in Syria, asserting that the U.S. should only act in its national security interests.

The moral outrage expressed by Secretary of State John Kerry, Cruz suggested, was not enough to launch a military attack against Syria.

“The United States Armed Forces doesn’t exist to be a policeman for the world and I certainly hope the reaction isn’t lobbing some cruise missiles in to disagree with Assad’s murderous actions,” he said.

The freshman senator indicated that could be a case for acting in Syria to stop the chemical weapons from falling into the hands of terrorists.

“The focus should be the only justifiable reason for U.S. military forces to be engaged is to protect our national security and sadly, that has been the missing variable from this administration’s approach from the beginning as they allowed Assad to slaughter over 100,000 of his people.”

Cruz also asserted that Obama and Kerry should go the U.S. Congress to make the case for military action.

“Secretary Kerry and the president have said they want to go to the United Nations for approval,” he said. “How going how about going to the United States Congress?”
