Republican frontrunner Donald Trump working to appear more 'presidential', has given his first in a planned series of foreign policy speeches.

FOX's Gurnal Scott has more:

The GOP frontrunner and self-proclaimed presumptive party nominee talked about his vision of America's role in the world, touching on what he called foolish decisions he says have led to upheaval in the Middle East:

(Trump) "Each of theses actions have helped to throw the region into chaos and give ISIS the space it needs to grow and prosper. Very bad."

Trump also stressed the need to support Israel. The speech would outline Trump's foreign policy "philosophy" so no specific strategies were discussed, but he says the goal is to "shake the rust off" America's dealings abroad.
