The United States will spend $7.5 billion -- a 50 percent increase -- to fund the fight against the Daesh terrorist group, Defense Secretary Ashton Carter said Tuesday, while he noted that over 3 billion dollars will be spent to counter Russian aggression.

"Because we are accelerating the campaign, (the Pentagon) is backing that up in our budget with a total of $7.5 billion dollars in 2017, 50 percent more than 2016," Carter said in a speech in Washington.

"This will be critical as our updated coalition military campaign plan takes hold" he said.

The United States will also spend $3.4 billion next year to counter "Russia's aggression" and boost the US presence in eastern European nations, Defense Secretary Ashton Carter said Tuesday.

"We're reinforcing our posture in Europe to support our NATO allies in the face of Russia's aggression," Carter said, noting that the $3.4 billion was a quadrupling of funds from last year.

"That'll fund a lot of things. More rotational US forces in Europe, more training and exercises with our allies, more prepositioned warfighting gear, and infrastructure improvements to support it."
