Is Hamas fit to operate as a government and run a country (or district)? ?

Not a chance. For starters, Hamas is an Islamic terrorist organisation. They can't live in peace with other Palestinian organisations let alone their neighbour Israel. They have no pride and do not have the welfare of the Palestinian people at heart. This is amply demonstrated by the fact that they use them as shields. Hamas is not a political party. It is a band of thugs and certainly not fit to govern. See what they did when they disagreed with Fatah. However, Hamas is running Gaza right now - running it into the ground.
