Contrary to what the Ukes wrote, the evidence is that approximately 12 aircraft were damaged, of which perhaps 7-8 were totally destroyed.

Russia will respond, but Russia's response isn't going to be to engage in stupid grandstanding attacks. It will hit military targets as it has consistently throughout the war because it is winning and has no need to engage in "terror attacks" (again, despite the reporting in the media that attempts to indicate otherwise; look at the civilian casualties for this war vis-à-vis, say, Gaza, or even the US invasion of Iraq).

I think you can expect a few Oreshnik hypersonic missiles at military factories, perhaps some more heavy infrastructure damage, and maybe even one or two spectacular strikes on airfields or ports, but the real fallout from this is going to be political. Russia now believes it has the evidence that the Kiev regime is a "terrorist organization" and Russia will demand full capitulation.

While Ukraine is holding on - barely - its manpower shortages are going to become so acute that the front will collapse, 1918-style. The question is really when, not if, that happens. The absolute outside time frame would be next summer if Ukraine goes to full mobilization of 18-26 year olds, but it could happen this year. When the front collapses, all hell will break loose in Ukraine as people turn on the government.
