The Arab Spring didn't result in +ve changes. It instead set the scene for Arab Winter ie. genocides. War instigated protests for the purposes of establishing puppet regimes- rarely last. True democracy is a home grown theocratic transition to become better human beings. It's a reflection of a population achieving milestones towards an enlightened society - Marx. Such things can't be bought and it certainly can't be rushed. At its basic, it needs to be authentically grassroots.
If the USA cared so much about retaining their superpower status they really ought to fix their own country starting with their political model. Redistribute wealth, a new tax system, promote small businesses, more support systems etc. abolish left/right politics which is perhaps one thing Trump can be credited for. I generally think of USA as a povo nation because it lacks a moral compass, people are so divided by race and everything else. It's really just a matter of time before the place becomes the quintessential tourism nation for homelessness. Marx made it clear communism is inevitable - the final political model towards an enlightened society (not one under an authoritarian rule like Stalin and North Korea). I see communism manifest in the USA by way of homeless communities sharing free resources etc. If Marx is correct then homelessness will be prevalent in the USA. I just hope it won't come so sudden it ends up like a Zombie apocalypse where people shoot each other and the currency exchange revolves around serums of all sorts ruled by scientists.
