class struggle pamphlets

I'm just curious if there are any good pamphlets available that would be something like a "class war for dummies" handbook, or "an intro to class war", that explained in the most concise and simplest possible terms what the class war is, why we need to fight it, and why it's a necessary feature of our current social relations and thus can't be ignored.

I've seen stuff in this vein (some good, some mediocre) on websites around the net, but I'd like to have something that I could be able to give to people.

Also, a "why nationalism is moronic", or "yay internationalism!" pamphlet would be great too, given the increasingly xenophobic and jingoist sentiments abound on this continent.
