stux, 
Personally I just hate any money spent on "borders to keep migrants out", often billions of Euros on stopping people :amaze:
If people are desperate they will come either way and they should! I would also if I was in that position
Instead put some more effort in finding and solving reasons why people migrate in the first place but do accept and help the ones that do come
A higher wall or an extra guard isn't gonna help anyone, on both sides
But that's just me 🤷
