Trump says of Iran: ‘Sometimes you have to use force’

President Donald Trump expressed disappointment about U.S. negotiations with Iran over its nuclear program and warned that “sometimes you have to use force,” amid a massive military presence in the region that could presage strikes on the Islamic Republic.

Trump has increased diplomatic and military pressure on Iran in the weeks since an Iranian crackdown on protesters, attempting to force the country’s rulers to forswear nuclear weapons and other activities Washington sees as destabilizing.
