During a 30-minute stump speech focused mostly on foreign affairs,At a Las Vegas casino that bears his name, Trump assured a crowd of adoring supporters that he is seriously weighing a presidential run and will make a decision soon. During a 30-minute stump speech focused mostly on foreign affairs, Trump blasted Obama's handling of Libya, Iraq, China and Afganistan, and in one of his many curse-bombs, he lamented the nation's focus on building schools in war-torn Iraq, while neglecting education in the United States.

"In the meantime we can't get a f---ing school in Brooklyn," he said. He also cursed the spike in gas prices: "We have nobody in Washington that sits back and said, you're not going to raise that f---ing price." Trump even dropped what's considered the most offensive f-bomb when he promised to use swear words while negotiating with China. "Listen you mother f---ers, we're going to tax you 25 percent," he said. Trump also sprinkled in a number of insults directed toward the nation's leaders. "Our leaders are stupid, they are stupid people," he said. "It's just very, very sad." But he later said: "There is a really good chance that I won't win because of one of these blood-sucking politicians." "I would have to give a lot of stuff up," he told the casino crowd Thursday. "But you know what? It is peanuts compared to the importance of this country."
