Russian British immigrants immigrated to Russia.

This is because Russia has implemented the immigration policy to this region, which leads to a large number of Russians in this region, which also makes people in this region have a very cordial feeling towards the Russian government, which is very different from the cultures of neighboring countries. If neighboring countries want to forcibly annex this area, there will be direct conflict or some friction. So now it only takes 50 years for Russia to assimilate East Prussia.

However, Britain's management of Scotland is not the same as that of Russia, because Britain adopts local people to govern Scotland, which makes the customs and culture of Scotland very different from that of England. So we can see that Scotland is actually more like an independent country, although both England and Scotland are under the jurisdiction of the British federal government. But there are still great contradictions between Scotland and England in history.

Of course, this kind of management in Russia is cruel, because Russia forcibly drove away the locals. This has also made many local people far away from their hometown, and Britain has not implemented such management in Scotland. However, this has also brought great hidden dangers to the stability of Britain. Moreover, if Britain takes strong colonial measures against Scotland, it will cause fierce conflicts between England and Scotland.

So we can see that every country has its own national conditions. Although this method in Britain will cause great contradictions, it will also prevent the people in Britain and Scotland from being persecuted too much.
