Honor Among Militant Islamic Groups?

This adds an interesting undertone to world politics: Chechen rebels are mad at Hamas for meeting with the Russian government. Apparently the Chechens thought that one militant Islamic group would stand up for another and see theirs as the same cause across the globe. This echoes the Islamic call to fight against the USSR in Afghanistan, as well as the Communist mantra of the late 1800's up to current times. The idea that people with similar ideals fighting in similar circumstances are united in spirit and really part of the same movement is a common sentiment among radicals. And when such is the case it represents a much greater threat to the people standing against the radical movement. Hamas's actions should give the western world a measure of relief because they show that Hamas, at least right now, is only focused on their domestic issues. They are still a militant group that advocates the eradication of Israel and as such should not be viewed in a friendly light. However, they are not ultra-radicals with a mission to spread their violence across the world to exact global change. Of course they may well become such if they are given power and they are able to find success in their domestic concerns. I think that the question now becomes how to keep these groups disconnected, how to make each group concerned only with their local issues, and then how to resolve those local issues so the radicals can melt back into normal citizens. As long as they are able to maintain an "us vs. them" mentality they are a threat to everyone who isn't part of their "us." When groups with different primary objectives but similar ideals group each other into the "us" it makes them much more dangerous, because then they are fighting over issues of ideals and no compromise can be achieved. As long as these groups can be limited to local concerns and be nailed down to voicing real grievances then they can be worked with and their grievances dealt with. When they become part of a global idealistic movement they cannot be reasoned with and therefore have to be opposed at every step with whatever means necessary.
