I genuinely hope something will come out of this, but knowing the slowness and reactive approach of European institutions I don’t have any hope.

Rather than talk, it would make much more sense to hold a formal conference after achieving results in agreed upon behind the scenes negotiations. Something along the lines of:

• Full blockage of occupied Königsberg. Banning of all russian traffic in the Baltic sea.
• Immediate sanctions of EU company executives servicing the russian market in any capacity (they know the shipments to Kyrgyzstan aren’t actually going to Kyrgyzstan, they are not stupid).
• Targetted massive ballistic strike (50+) on russia military and C2 installation in cooperation with Ukraine to give cover (perhaps even Lubyanka if it makes sense). Just lie and say it’s recently developed Ukrainian ballistics.
• By this point it would make sense to at least send covert military personal into Europe, make it limited to AA coverage in Western/Central Ukraine if needed.

I recognize that this may sound unrealistic, but most (all?) geopolticial achievements/breakthroughs/realignments were done with courage and a desire to win. Not “bla bla” or “but what about this or that”.
