When Hamas entered parliament, it did so under the slogan: Islam is the solution. When the people decided to vote for it, they believed that Islam can solve their economic, social and political problems as well their military battles against the occupation.
All the better reason to starve them of funding to show the goat lovers "islam is not the solution" instead of supporting the swines jihad with global welfare so they need not face the necessity to evolve away from mohamMADan ideology.
