I do not know who it is "we", but Trump is certainly NOT trying to stop sending soldiers abroad. Instead, it is using them to attack Venezuela, Iran, Cuba, boats on the see cause killing is fun and to threaten Greenland. Iran is completely pointless and expensive war in particular. Also, pressuring Ukraine to give up more territory then Russia took is NOT "stopping to mess in other peoples affairs" either.

Also, what Vance is doing in Europe is not "stopping to mess in other peoples affairs" but instead "meddling into politics trying to make far right happen".

Trade war with Canada and numerous attempts to "punish" other countries for prosecuting corruption are also meddling.
