As Russia makes gains in the whole Donetsk region in eastern Ukraine the UK approves use of its long range missiles inside Russia. Biden is on the verge of making a similar decision as Iran sends long range ballistic missiles to Russia according to reports in NYT. Use of American long range missiles is not expected to affect Russia's overall military position in the Donetsk region in the east. The US and president Biden has only reluctantly provided support for use of US weapons systems to not risk escalating the war. Even artillery on the Russian side was off the list of approved use till Russia used it in Kharkiv border region at which point it was approved.

Russians see Kiev as the origin of the Russian State in the 1400's, and eastern region of Donetsk as Russian if western Ukraine seeks to join NATO and EU. Britain has opposed Russia since 1750 as it saw Russia as the threat to an Empire it was building in South Asia, in India that financially supported its Empire worldwide. Britain has a long history of engaging Russia in conflict to protect British trade interests and expand its imperial influence as in the Crimean War fought in 1850's against Russia with the French to gain control of the Ottoman Empire and its Arab states for its trade and imperial interests.

Republicans other than Mr. Trump and his supporters are for stronger support to Ukraine following US policy of opposing invasion to achieve military goals since 1900 against the Japanese in China and the Vietnam War was fought on the same basis in the 1960's considering the South Vietnamese state as an independent republic, just  invaded by the north, by North Vietnam, just as the US had done in the Korean War between North and South Korea. In the Vietnam War nationalism played apart with the Vietnamese nationalism prevailing by 1970.
