In an attempt to reshape the narrative of the presidential campaign, Republican presidential nominee Donald Trump took issue with what is perceived to be Hillary Clinton’s strength, America’s foreign policy.

“America is far less safe – and the world is far less stable – than when Obama made the decision to put Hillary Clinton in charge of America’s foreign policy,” Trump said during his acceptance speech at the Republican National Convention in Cleveland on Thursday.

Trump went on to say that he is certain that President Barack Obama “truly regrets” his decision to appoint her as secretary of state in 2009. Referring to comments made by Clinton’s chief rival in the Democratic primary, Bernie Sanders, Trump charged, “Her bad instincts and her bad judgment are what caused many of the disasters unfolding today.”

Listing off the countries that are currently undergoing unrest as a result of her record as America’s top diplomat, Trump claimed that since Hillary assumed office, “Iran is on the path to nuclear weapons.”

“As long as we are led by politicians who will not put America First, then we can be assured that other nations will not treat America with respect,” according to the Republican presidential nominee. “This will all change when I take office.”

Trump also promised to work with Israel, “our greatest ally in the region,” to destroy ISIS and defeat Islamic terror.
