Former President Trump has proposed a plan to arm Ukraine indirectly, threatening Russia with tariffs if the conflict escalates. The proposal involves the US selling weapons to NATO member countries, who would then be responsible for transferring the arms to Ukraine. This approach aims to provide Ukraine with necessary military support while potentially mitigating direct confrontation between the US and Russia. The threat of tariffs serves as a deterrent, intended to discourage further Russian aggression. The plan's effectiveness hinges on NATO allies' willingness to participate and Russia's response to the indirect arms supply.
