Yesterday, Thursday, Finland also announced a fully negotiated agreement with the US. It will be formally signed on Monday and will give the US access to fifteen Finnish military bases. Several of these are in Northern Finland, including Ivalo, Rovajärvi, Rovaniemi, Tervola and Veitsiluoto.
In total, Norway, Sweden, and Finland have opened 36 military bases for US forces and weapons. The agreements are bilateral, i.e., between the US and the individual country, and not a NATO agreement.
The question of the placement of American nuclear weapons in Sweden and Finland has not been regulated through the agreement. In contrast to the Norwegian base and nuclear policy, the agreements do not explicitly ban the placement of such weapons. The probability of it happening is nonetheless small. Modern nuclear weapons are quickly moved if deemed necessary.
The conclusion is that Russia's war against Ukraine has fundamentally changed the military use of the High North, and it has done so in a very short amount of time.
The aim of this US-Nordic strength-building in the North is to deter Russia from an attack, as we have seen Russia willing to do in Ukraine.
