I don't understand how Israel has ben able to build so many illegal settlements in the occupied territories.  It seems to me that a viable Palestinian state is almost impossible with these foreign outposts in place.  These settlements and the people in them must feel like a complete insult to the occupied Palestinians and part of a larger strategy of taking more land from them.  I want to know if anyone can explain the nuts and bolts of how Israel manage to do this.  I understand that lots of people have strong feeling on either side of this issue but please try and give me a solid legal and rational response.
