From the Wikipedia article on Russia's playbook: "Foundations of Geopolitics"
Ukraine (except Western Ukraine) should be annexed by Russia because "Ukraine as a state has no geopolitical meaning, no particular cultural import or universal significance, no geographic uniqueness, no ethnic exclusiveness, its certain territorial ambitions represents an enormous danger for all of Eurasia and, without resolving the Ukrainian problem, it is in general senseless to speak about continental politics". Ukraine should not be allowed to remain independent, unless it is cordon sanitaire, which would be inadmissible according to Western political standards. As mentioned, Western Ukraine (comprising the regions of Volynia, Galicia, and Transcarpathia), considering its Catholic-majority population, are permitted to form an independent federation of Western Ukraine but should not be under Atlanticist control.
No one said anything about pulling SEA into a war. No one said anything about Europe forcing SEA like colonizers. Shit has changed in the past few decades.
NATO is a mutual defense pact. He's just talking about setting up a similar defense pact in SEA and East Asia.
As mentioned, SEA is relevant because those nations have the potential to be China's Ukraine.
SEA is likely to be open to some kind of mutual defense pact, as China has been testing borders for a long time, especially in the South China Sea. I believe the only reason they haven't is because of smaller military, trade relations with China, and the unlikely support of East Asia. East Asia looks down on SEA. If Europe engages in more trade, offers military support, and mediates improved relations between SEA and East Asia, I think a mutual defense pact is all but given. That said, the trade and military support are a tall order.
In any case, this is basically reciprocal action. See the comment about dogs shitting in yards.
