Political situations can change rapidly, and it's important to rely on up-to-date and credible news sources for the latest information. As for the issue of warranties and guarantees on products, it would depend on the specific policies and agreements between the involved parties. If any such scenario were to arise, it would likely be subject to negotiation and international laws.
If you have concerns about warranties or guarantees on products you purchased, I recommend reaching out to the company or seller from whom you made the purchase for clarification and support.
