I'm not sure what the bit about segregation comes from. In a wartime situation, potential enemy aliens - especially those in senior government positions - need to be vetted for their loyalty to the state. During WWII, this meant the internment of Japanese citizens along with small numbers of German and Italian nationals. It occurred all over the world, not just in the US, and remains standard practice in most countries. That is why you will not find Arabs in make-or-break government positions in Israel, just as you won't find Muslims in equivalent positions in India.
For a more recent example, it is empirical fact that Slovenes, Croats and Bosnians defected to their ethnic groups' respective Territorial Defense units within days of the Wars of Partition. For Ukraine's government to not consider the possibility of treachery from within would be foolhardy in the extreme.
Oh, Pleeeezzzze, no one in their right mind buys that and anyone selling it is either a half-wit or a dedicated propagandist with no regard for the facts.
For starters, what percentage of the Ukraine is "ethnic Russian", a threat to the State for having married an "ethnic Russian", or the next door neighbor of an "ethnic Russian" and therefore a potential sympathizer?
That dog that won't hunt and it's nothing but a lame attempt disguise the initial steps toward the goal of expelling all "ethnic Russians" from the Ukraine exactly like the Nazi wannabes are demanding. Not that I"m the least bit surprised at the lame attempt to disguise the real goal which is implementing the "final solution" to the "ethnic Russian" problem.
As I've said before, I'm 100% behind diverting all military aid of any kind from all Muslim states and sending it to the Ukraine. How the current "government" could manage to hang on to any of it with units defecting or deserting one after another I don't know, but that's the extent of what this country should do and only if it's actually diverted from what is now going to Iz Lame ists.
Not that Ukraine "deserves" such support, just that it's a lesser waste of tax money than passing it out to Mooze Lame scum and we can eventually buy it back for next to nothing instead of having it distributed as jihadists see fit.
