I doubt that Russia concedes $300B simply as a payment aimed at post-ceasefire Ukrainian reconstruction. The colossal geopolitical rapprochement which Trump has initiated just urges Kremlin to demand better conditions of the settlement. More likely, the US will obtain ROU assets in exchange for a share of Ukrainian mineral wealth that is currently unreachable to Kiev (4 partially annexed provinces). After this, US may get their brokerage, say, 50 % or even 75 % (which will depend of avarice, stupidity, and hauteur of Zelensky), while the rest may be placed into the fund created specially for the rehabilitation of Ukraine, under the most strict control directly from Trump-Vance-Musk's administration. Of course, any compradors, aiders and abettors of Biden-Blinken's dirty tricks during ten plus years of their pet business project and, specifically, three years during which conveyor belt of Ukraine aid was working incessantly, should be sanctioned, investigated, audited, and jailed. Speaking about Zelensky and his cronies, I think they have little choice but Hobson’s.
Zelensky has nobody to blame for it but himself, Boris Johnson, and Biden-Harris administration: the war could, and had to, be shut down already in Istanbul. Note how a (supposedly) Russian drone strike at Chernobyl nuclear plant sunk calmly into deep waters of international news traffic? Before the demise of USAID et al., such an event could have spawned a wonderful pretext for slipping out of peace talks, whichever warmongering faction sent the drone. (Who, exactly, it was, is of nobody’s interest.)
Hadn’t we seen it before, in another time and place?
