If they were to walk to the USA border, it would be the exact distance Syrians are walking to get to Greece, in fact it would be closer. Imagine NGOs waiting for them at the border to help them "for their trouble to get to the USA because of their circumstances". That's the logic of labeling illegal immigrants as refugees. They are perfectly safe in Turkey where they initially find refuge from the war. When they leave Turkey to go to Europe, they are no longer running away from danger but are in search of a better life. That's understandable, but illegal nonetheless. For went should the Syrians be given priority for an exception to their desire for illegal immigration and not want other of the 2.5 billion people on this planet with similar or worse circumstances?
