Across the English Channel, the white cliffs of the U.K beckon. On fine days, men and women with children in their arms and determination in their eyes can see the shoreline of what they believe will be a promised land as they attempt the perilous crossing clandestinely, ditching belongings to squeeze aboard flimsy inflatable boats that set to sea from northern France. In a flash, on one recent crossing attempt, French police swooped in with knives, wading into the water and slashing at the boat's thin rubber — literally deflating the migrants' hopes and dreams.
