I mean, historical precedents for land grabs abound, but after the 1918 Wilson Doctrine (a US creation, btw) there is nothing. Colonialism is over and blatant imperialism doesn't work; we hold this as self-evident truth.

Then again, certain governments continue to act like we were still in the XIX century so "might makes right" (Russia, Israel, China, Morocco, Turkey...). If one is not ashamed to be in such an esteemed company, everything is possible.
