Recently, Trump threat to Russia to stop the war (Ukraine-Russia) with in 50 days. Trump threatened them that if they cannot reach an agreement to stop the war within this period, then 100% tariffs will be imposed on their products. The important thing now is how much this tariff will affect Russia. We know that since the war started, Russia has been restricted in various ways and there are also bans on the export of several of their products. If again 100% tariff is imposed on this country, will it have any effect on stopping the war?
In 2024, Russia's total trade was about $3 billion. Whereas in 2021, US imports from Russia were $29 billion. Now, if 100% trade tariffs were imposed on $3 billion trade, would Russia take it seriously and stop the war?

You would need to have a look at WHAT does the US import from Ruzzia. For example, It is largely irrelevant if you put tariffs on Ruzzian oil because the market is global and someone else buys (and thanks you for the discount), if you put it on agricultural products... same, Ruzzia sells to others...
And guess what... one of the major imports are fertilisers and Trump cannot afford to have the agricultural sector of the US against him due to higher prices.
The strategy to put economic pressure is quite difficult unless you are willing to harm yourself in the process.
