The UK guarantees military support to Finland and Sweden and will send troops to protect them in the event of "Russian aggression". The deployment of nuclear weapons on the territory of these countries is not excluded. A number of relevant statements were made by Boris Johnson following his visit to the region.
The British Prime Minister made an official visit to Sweden and Finland on the eve of the submission of applications for NATO membership by these countries. It seems that the purpose of this trip was the intention to push these countries to the "right" decision, therefore the UK guaranteed protection to Finns and Swedes from "aggressive Russians". And we can say that it worked, today Finnish President Sauli Niinisto and Prime Minister Sanna Marin have already spoken in favor of joining the alliance. This was reported by the "Military Review" in one of its news materials.
During his visit to the region, Johnson reportedly signed two documents on mutual guarantees with Finland and Sweden. If we remove all the verbal husk like "our partnership is reaching a new height," then the main essence of the signed agreement is that the UK guarantees the Swedes and Finns protection from "aggressive Russia." According to Johnson's statement, in the event of an attack on these countries, British troops will immediately follow to repel the attack. It is worth noting that the guarantees are mutual, so if the UK is attacked by "evil Russians", the Swedes and Finns should also hurry to the British to help.
According to the British press, Johnson expressed serious intentions to consider the possibility of deploying even nuclear weapons on the territory of the Scandinavian countries, ostensibly to protect their sovereignty. However, the British Prime minister did not explain what kind of weapons he was going to place.
By the way, the press service of the British Prime Minister called the assumptions that Johnson was trying to persuade Finland and Sweden to join NATO by his visit disinformation. As explained in London, this "does not correspond to reality."
