You didn’t read the article. Islamic governments have cut off Hamas’s funding, so Hamas is running out of missiles and can’t pay its government civil servants.
Right. So what is Hamas going to do to get more funding? How will it convince Muslims that it is relevant and should be supported?
Hamas appears to be operating on the basis that the reason they don't have enough funding, is because they have not been sufficiently diligent on conducting Jihad against Israel.
