President Barack Obama of the United States said, Sunday, that scores of European citizens fighting abroad could use passports to enter US without a visa to carry out attacks.
Obama told ABC's This Week, "Now, we are spending a lot of time, and we have been for years, making sure we are improving intelligence to respond to that. We have to improve our surveillance, reconnaissance, intelligence there. Special forces are going to have a role. And there are going to be times where we take strikes against organizations that could do us harm."
