"“The territorial integrity of Ukraine has never been, and will never be, a subject for discussion or compromise. "
But that's not what history shows: Crimea was precisely the subject for not only discussion and compromise when the territory, which had been recognised as part of the RSFSR (Russia) within the Soviet Union, was transferred as a gift to the Ukrainian SSR, due to 'close ties', to commemorate the Union of Russia and Ukraine Tercentenary in 1954 — nothing more, nor less, nor other than a discussion (among the Soviet elite behind closed doors) for the purpose of compromise — a vanity gesture to pacify opposition for Khrushyev pacify opposition and feel more secure in his insecure new role. Those interested, I would suggest, might be best to read, 'Why Did Russia Give Away Crimea Sixty Years Ago?' by Mark Kramer, Director of Cold War Studies at Harvard University for the Wilson Centre (https://www.wilsoncenter.org).

(Almost) forgot:
"..."the ‘smartest man in the room’..."
I understand he studied in the UK from the age of ~18 to 29 and considers his English to be indistinguishable from that of a native speaker.
That's pretty smart!
Sikorski is alas, almost a decade too late with his suggestion.
