AlQa'dah 08, 1435, September 03, 2014, SPA -- European members of NATO need to do their fair share of defence spending to bolster the alliance, U.S. President Obama told a news conference in Tallinn on Wednesday, a day before the start of a NATO summit, according to Reuters. Obama said the United States has already bolstered its military activities in the Baltics -- three former Soviet republics now part of NATO and the EU -- and it was continuously rotating both personnel and aircraft through the region.
