[quote=Goldmarble]Any country without a military, will be invaded and conquered by a neighbour, with no more reason than because it can, in this modern age.

There are numerous countries with no standing military that haven't been invaded/conquered by a neighbour.

[quote=Jannah]
Ukraine wasn't annexed. Crimea wasn't either. It's majority ethnic Russian and actually was Russian territory up until Khrushchev gave it to what was the Ukrainian SSR.Also, Liechtenstein is a poor example since it's surrounded by one of the most neutral countries in the world, Switzerland.

Crimea was annexed by the Russian Federation. Whether you believe the annexation to be legitimate or reasonable is entirely irrelevant. It occurred regardless of your beliefs on its legality, since the action of annexation is independent of the reasoning therefore.
