It's quite inconsistent position.
If you think Russia during Chechen Wars were already dangerous enough to fear "little green men", then how exactly do you explain them not appearing in your country back then? What inhibition evaporated in 2000s to make you more fearful, given that military was there (and active) all along?

Yellow Vests. Haven't seen any EU dislikes there.
Ah, so you primarily fear people of your own country getting outside help out of xenophobia? Well, that makes a lot more sense given your disdain for ethnic minorities.
Your culture and country is simply not significant enough to forcefully assimilate bigger ethos; and refusing to give them their space out of naked nationalism is foolish.
