why do you think this? it's next to impossible to completely stop piecemeal border crossings. but beyond a certain scale, it becomes something that militaries can oppose directly. are you suggesting the europeans would not have the stomach for military action against migrants, or that the migrants would somehow defeat them in sheer numbers? if it's the former, I would point out that were are already seeing questionable events with migrant ships in the mediterranean.
