In tonight’s Talking Points Memo, Bill O’Reilly said that President Obama is not a natural leader, and a lack of leadership is hurting the nation as threats from ISIS and Russia grow ever more serious.

O’Reilly said that his new book, "Killing Patton," which comes out two weeks from tomorrow, is about leadership and what happens to strong leaders when they make powerful enemies.

"General Patton, Winston Churchill, FDR, even Hitler and Stalin figure prominent in the book," O'Reilly said. "Barack Obama should read 'Killing Patton.' I hope he does, because we need strong leadership in America right now."

"We need to be inspired. Sadly, President Obama is not fulfilling that mandate."

"The Factor" host pointed to Obama going golfing moments after announcing the beheading of American journalist James Foley.

"It’s obvious to most people, you don't play golf after announcing the gruesome beheading of an American citizen," O'Reilly said.

"The president is not a natural leader, and that is harming the nation," O'Reilly stated. "Right now, the world needs to be inspired to take action against Islamic terrorism and the Russian villain PutinThe world needs a strong leader to mobilize action against those threats."

He said that Obama doesn't understand that fact, as illuminated by the president making conflicting statements about ISIS and failing to punish Russia in effective ways.

With savages murdering innocent people all over the world and U.S. allies apparently not interested in pursuing global justice, it becomes vitally important for America to lead the world.

According to O'Reilly, that requires a strong point of view from Washington.

"This week, Mr. Obama will make yet another speech about how he will finally confront the ISIS threat," O'Reilly concluded.

"We hope he includes Putin in that speech, and we hope that finally after all this time Barack Obama will show some passion, some urgency, some determination to eradicate evil in ways that are smart and effective."
