Russia and Ukraine flashpoint

[SecondWar]

In regards to escalation, I’m wondering if similar conflicts elsewhere could ultimately end up fuelling this.
Last week there was a flare-up in Nagorno-Karabakh, which ultimate ended in 24 hours (though the aftermath seems far from pretty) and now Serbia seems to be massing troops on its border with Kosovo.
Serbia counts Russia as a key ally and Nato has troops stationed in Kosovo so it would end up with the same powers at play even if the conflicts aren’t directly related.
