Trump's plan is adding condition to Ukraine aid, i.e. Ukraine, in order to continue to get aid from US, has to have peace talk with Russia. This gives US a strategic goal in supporting Ukraine - peace.
By contrast, Biden's aid is "as long as Ukraine needs" which has no strategic goal. It will only lead to endless war and eventually to last Ukrainian who still needs US aid and we still have to support him. This is not strategy. This is emotion.
