You typically need to notify other members of a treaty of your withdrawal, and then there's some time delay until you're no longer bound by the terms. You can't just secretly withdraw, or treaties wouldn't be very meaningful.
EDIT: Yeah. The submitted article says that it happens in six months from today, and here's the treaty text on withdrawal:
Each State Party shall, in exercising its national sovereignty, have the right to withdraw from this Convention. It shall give notice of such withdrawal to all other States Parties, to the Depositary and to the United Nations Security Council. Such instrument of withdrawal shall include a full explanation of the reasons motivating this withdrawal.
Such withdrawal shall only take effect six months after the receipt of the instrument of
withdrawal by the Depositary. If, however, on the expiry of that six- month period, the
withdrawing State Party is engaged in an armed conflict, the withdrawal shall not take effect before the end of the armed conflict.
The withdrawal of a State Party from this Convention shall not in any way affect the duty of States to continue fulfilling the obligations assumed under any relevant rules of international law.
Point 3 looks like a pretty obvious poison pill. That is: Russia could conceivably start some sort of grey-zone conflict with Finland before the 6-month period, and thus (per international law) tie Finland’s hands in their use of defensive land mines.
In Finland’s shoes, it’d be prudent to just go “yeah we’re breaking the treaty, and were specifically ignoring Article 20 Section 3 due to urgent national security considerations”.
Absolutely! You are quite right. However, my interpretation of this message is not necessarily "we might reconsider our stance on troop mines". Rather it is: "we will go to any lengths, even those we find barbaric and cruel, to defend our nation". Although on the face of it, it is the wording of the agreement that sets the formalities.
Mines are NOT "deterrent". Strong army? Yes. Nuclear weapons? Yes. Mines are a minor nuisance during the war. Makes things uncomfortable, might slow down enemy movement a bit but that's it. You can't say to the potential enemy "Forget about attacking -- we have mines near the border".
you are just trying to picture a whole group of people to be like you say again. also poorly elaborated and mispelling i wouldnt be surprised if you are from a troll farm
