If the Russians keep losing so many men, munitions, resources on a daily/monthly basis and their economy continues to deteriorate in the absence of a negotiated settlement or "peace agreement" even if these discussions last for months, I'm not entirely sure Putin and his cronies can continually keep playing hardball and making outrageous, unrealistic demands as preconditions for a peace EU, NATO, hell, even "bro-friend" Trump knows they won't honor 4-5 years from now.
