If people erroneously believe that they are doomed *because* of colonialism, I never said that. I did say that the West drew some utterly unexplainable borders when they gave up colonialism. And that has caused ongoing problems.
Who's responsible for the problems? The West has to take most of the responsibility.
Who's responsible for fixing the problems? Well, if the former colonies don't, they will never have the sovereignity and prosperity they thought they were getting when the colonists left.
We don't disagree much. I just think the colonizers have more of the blame than you do.
"I never said that. I did say that the West drew some utterly unexplainable borders when they gave up colonialism. And that has caused ongoing problems. Who's responsible for the problems? The West has to take most of the responsibility." 
Nonsense.
Logically, if the *borders* were the problem, then those colonies would have been unsuccessful even when they were being run by the Europeans. They had the same borders back then, after all.
That's clearly not the case. Zimbabwe was a global food EXPORTER under colonial rule, yet now foreign aid into Zimbabwe is its largest single "industry," hardly a good sign.
Moreover, not all colonies had arbitrary borders drawn onto maps for them by Europeans. Some colonies/nations still have their natural borders, for instance (e.g. Jamaica, Bermuda, etc.).
So again, logically speaking, clearly arbitrary borders can't explain Jamaica and Bermuda...so the whole "European borders caused all of our woes" argument fails to fly by that route, either.
