Why Is It Our Problem?

[makeo]

Frankly I don't feel it is our fight. I am not even sure why the USSR dissolved. I understood it collapsed but the public details do not add up to me.

IMO, Russia hass the right to take all of Ukraine right now, the president, democratically elected by the people, went to Russia if he wants Russia army to invade and reinstall him as the leader, he has the right to do so. If the president of mexico was overthrown in a popular uprising and begged the usa to reinstall him, I'd have no issue sending in us troops to do the job. To protect democracy.

That's fine as an initial emotional viewpoint.
The question however becomes slightly more complicated when you actually examine it.
While there has not been a due legal process of impeachment, the Ukraine parliament, which is the duly elected body, and as much as anything represents democracy, unanimously voted him out on a concentration of power being misused mandate.

Where does legal technicalities end and democracy start?
Well, most would contend in international law, that it starts with self determination on legally elected bodies.
And based on that, he's f*cked, and the argument is a mere technicality.
