Why is most of Europe not safe for those fleeing surely once they are out of the war zone and in a safe haven the need to continue to flee stops and therefore there is no requirement to even think about crossing the channel
You are right. What the French should be doing is asking those in Calais whether they want to claim asylum in France, since as you are say they are in a safe country. If they don't want to claim asylum in France, then the French should be returning them to their own countries not allowing them to set up camp there in the hope of coming here.
