The European NATO allies will always be able to rely on the United States,  President Barack Obama said during a press conference summing up NAO summit in Warsaw.

“What will never change: the unwavering commitment of the United States to the security and defense of Europe,” he emphasized.

The American leader noted that for the fist time in 70 years since NATO has been established, the Alliance members are simultaneously faced with so many challenges, such as the Islamic State, Russia’s policy on Ukraine, migrant crisis and Brexit.
