Syria is Russia’s Vietnam?
No, Afghanistan was (where Russians themselves were dying). Not the only similarity; both the USSR in Afghanistan and the US in South Vietnam were invited in by the existing government, and those governments survived a few years on their own after each of us left. For some reason, we referred to the USSR’s presence in Afghanistan as an “invasion”.
I thought Afghanistan was Russia's Vietnam, and Syria was Russia's Iraq, and Russia's Afghanistan is America's Afghanistan.
