House Homeland Security Committee Chairman Michael McCaul (R-Texas) raised the specter of "submarine warfare" from Russia while making comments on the downing of Malaysia Airlines Flight 17.
"Mr. Putin is returning to a Cold War mentality," McCaul said. "You said this nationalistic pride [in Russia], a resurgence to regain the glory of the old days … It's not the Al-Qaeda threat, but it's the threat of brute force."
Russia's role in destabilizing eastern Ukraine appeared to culminate last week when Flight 17 went down in territory controlled by separatists with ties to the Kremlin.
