Just briefly skimmed through all this so don't know if something like this was said, but basically, if life in america is continuing as normal in the sense that we all have seder and work and school, etc.. that in the past has needed a vacation to recoup and refresh to continue doing so, then why is it different now? Assuming what you're doing is within the torah framework, we need to do what we need to do to help ourselves be functional human beings. It would definitely seem appropriate to formulate the trip around something meaningful or not being completely leitzanus as if nothing is going on, but if someone goes to florida every year for january break because thats where they feel they will get energy to keep going until pesach, so be it, especially being an ibur yar and everyone having an extra month.
People can take this situation as they feel, but for all intents and purposes, the war is Bli Eyin Hara not going on in America, and while we have to feel for those suffering we also have to appreciate that we are not those people. And their situation is not our situation to live out for ourselves but rather to daven for them and feel their pain. Not superfically, really feel their pain because we're all brothers. But BH we have a vacation and we have a responsibility to keep ourselves and our families functioning. So enjoy but don't forget about what is going on
