I'm very glad that you were able to understand what I was getting at. I wrote this poem to embody two themes; the one you have so clearly pointed out, and another. I also wanted to comment on how the global rise in nationalism (Trump, Theresa May, and others) can be a dangerous thing. Historically, nationalism only leads to conflict, hence the title. ACU stands for Army Combat Uniform and is what American army uniforms (The digital camo, not dress uniforms) are called. The "sinister pattern" is both the oppressing model of capitalism and military camo. Both represent an oppressive and exploitative governmental system, and both lead to further suffering for both the people wearing the pattern and those who oppose them.
