Why do Muslims join kuffar armies?

Is “better living” more important than not supporting “enemies of Islam”? Just look at the examples set by Osama bin Laden and co.
It is obvious you have option to leave these kuffar enemies of Islam. But you chose to help them kill Muslims.

Oh please, don’t denigrate the word “Hijrat”, after what you guys have done to the word “jihad”. I shouldn’t even need to explain why.

What is so negative about these “mujahideen”?
I am bringing them in discussion because for people like you they are the true Muslims. Ask cricketplaya. So you should be helping these so-called “true Muslims” instead of helping kuffar enemies of Islam.
