Our leadership are fools.
When you go to war, go to war.
Fight the war, win the war and come home.
Don't try to drag a dysfunctional, regressive culture into the 21st century by buying them new airplanes and sewerage plants.
They don't appreciate it and don't want their savage culture replaced with an enlightened democracy.
Their society is focused on destruction, not building and advancement.
They don't respect anything but brute force and power.
Well what they still do with their left hands is still prevalent today...
So sewage plants are kinda one of those things they choose to not take advantage of...Or toilet paper for that matter...
