This kind of attack matches Putin's "gray zone" approach, and would be just the thing for him to do to demonstrate his power (or even just out of spite) if he is pressured into a ceasefire or peace agreement in Ukraine. 

The PRC definitely has related ambitions, and could pull it off with their standard approach (bribing senior officials, offering trade deals, etc.).

After the disastrous consequences of his invasion of Ukraine, Putin will hopefully be deterred from similar actions for other countries.

Very unlikely given the timeline.

European nations can barely muster this kind of force for their own defense, and thus would be hard-pressed to deploy one to Ukraine. Also, persistent issues such as risk aversion, fear of escalation, slow decisionmaking, lack of logistics capabilities, etc. will make this even less likely.

I don't think the European nations can overcome their related issues (slow decisionmaking, anti-defense mindset/culture, fear of escalation, Russian-controlled people in key positions, etc.) and come through with this kind of substantial commitment.

The creation of the Space Force is one of President Trump's achievements and thus he and his team are likely to push for generous funding. Beyond that, space is also an area of increasing importance to national security and national prosperity, and the USSF plays an important role for both, so they should receive more funding. 

ASAT technology is proliferating, and the benefits to those using them are so obvious that some of our adversaries may feel tempted to use them, likely as a real-world test or capability demonstration, or as a "shot across the bow" in support of a terrestrial conflict. 

Given the pressure applied by the US administration, both countries will hopefully see it as being in their best interest to cease hostilities. Accidental deaths e.g. from mines during the forecast period are unlikely to reach 20 or more.
