U.S. To Deepen Security Relationship With India: Pentagon

"Russia's military actions are undermining regional security directly and through proxy forces. These actions violate numerous agreements that Russia has signed in which it committed to act in accordance with international norms," it said.

The Pentagon said Iran also poses strategic challenges to the international community. "It is pursuing nuclear and missile delivery technologies despite repeated United Nations Security Council resolutions demanding that it cease such efforts," it said, adding that North Korea's pursuit of nuclear weapons and ballistic missile technologies also contradicts repeated demands by the international community to cease such efforts.

"None of these nations are believed to be seeking direct military conflict with the United States or our allies. Nonetheless, they each pose serious security concerns which the international community is working to collectively address by way of common policies, shared messages, and coordinated action," the Pentagon said.
