Group vs Government

What would a government do if groups of people started arriving in a country and say "This is where we were destined to live, will you leave now." The government would probably laugh it off and get them off the land because the proposal in itself is so foolish, it isn't worth a discussion. So, the group now gets down to business, because they do honestly believe that this is their destiny, just like a madman would believe his philosophies with all his heart, no matter who says otherwise. The group starts planning, strategising, gathers forces and starts attacking at the civilians in the country. The poor things have no alternative but to run for they never envisioned such a scenario.The government is losing land and people and furiously tries to put out this "uprising" if thats what it can be called. Civilians are still on the run, the group instates its own government and declares to be an independent country. The world decides to poke its nose into the whole affair finally and the emerging super power with all its brilliance decides to support the 'group'. The government rallies to its neighboring countries for support. War. Fights. Fears. Displacements. Loss of life. Loss of hope.
People thrown out of their own homes and living as refugees in a time where war should not have happened at all, esp. when you have a UN body.
The strength of the group increases, they flock in from the rest of the world where their very existence is being threatened, so the land looks very lucrative. Now this group is a very intelligent sect. They have the brains, they have sympathy from the world because they were being seriously discriminated upon, they have the support of the super power.They gain power, extend control, make thousands more homeless while they make homes for their kind.
The poor refugees cant sit quiet now, can they. So, they start poking the elephant with pins. The result, they get branded as terrorists. The whole world, who probably never knew this country even existed, starts looking at this development closely. So, here we have terrorists who are agonizing their neighbors for not much apparent reason. We have pictures of a people who are suicide bombers and what not floating around. People killing others and not afraid to lay down their own life in the process. What is it that they have lost ? Why is it so important to them? There isn't even a full fledged war. And what is it that they intend to achieve with the only superpower and the UN not on its side? What guts do they have to continue with pins? and why don't they give up? But, since the label says 'Terrorists' , they are the bad guys, right?
Imagine, a group of Buddhists enter America and say, "This is where Buddha is going to be reborn and we are going to set up a kingdom of Buddhists, will you leave now", what do you think the government would do?
Will it support them the way it has Israel? Will it make US citizens terrorists?
