#1 Americans policy in the middle east is a total washout. The repercussions of it is starting to rear its head.
#2 The rigidity of the staunch followers of religions in following the rule of the land. I mean the stupid followers. Your country men are also your brethren sort of attitude - not just people of your faith. In the highly inter-connected world if we don't shed hatred and don't learn to be tolerant towards other faiths - we will be doomed.
#3 The voting process needs a re-look. Look what happened with boaty mcboatface, brexit and now US polls. Age shouldn't be the only criteria to allow someone in voting process. I don't think this is a easy problem to solve but we definitely need a rethink.
