FORT HOOD, Texas — In a speech to the nation at a military base rocked by another shooting which left three dead and 16 wounded, President Obama issued a defiant call to arms against the enemies of the United States while saying the attack was "definitely an act of terrorism."

He went on to vow that all those who attacked Americans on their own soil would be brought to justice.

"We have been fighting a war overseas for more than a decade," Obama said, "But sadly, an estimated 2.6 million potential terrorists now live among us."

Following the speech, many of the president's supporters hailed Obama as a strong wartime leader, citing his declaration that a ‘red line’ had been drawn and that any further attacks from terrorists on U.S. soil would draw a firm rebuke and censure in the United Nations.
