I do live my life differently because of the realities of the world. First and foremost, I pay attention to what's happening in the world, and I vote for people whom I believe will respond to those issues responsibly with the best interest of our country in mind. Unfortunately, my candidates did not win recently, and it appears that we have a large section of the country who doesn't very much like our country, but that's a different topic. I also try to live a sustainable life, so if the lights go off because of an EMP, or a simply a network/grid shutdown, my family and I will survive. My kids may group up in suburbia, but they will not be dependent on suburbia.
Moreover, I am raising my kids to be adults who are aware of the world around them, and to understand how to filter out the ignorant opinions that media, politicians, Karens, and internet forums will spew at them. My kids great up overseas for some time. They understand why the US is truly amazing and unique in it's liberties and freedoms. Understanding the real threats in the world is definitely impacting how I raise my kids, and I value my parenting task as possibly the most important and world changing thing I might do in my life. If my kids impact a single life because of wisdom they learned in childhood, it'll have been worth it.
Beyond that, I study facts and history. The American way of international relations since WWII has been to make sure other country's problems stay in other countries. You call Ukraine a quagmire for Russia. It wouldn't be a quagmire without US involvement. If you don't understand that, go read about Chinese involvement in Vietnam, or US involvement in 1980's Afghanistan, or the French Foreign Legion, or how Rome ran it's empire. History is littered with precedent. The reason America is what it is today is because we (typically) refuse to wait until the fight comes to us. If you don't think Russia would love to kneecap the US, think again. It wouldn't occur in the ways many imagine with conventional forces and red dawn, but rather with infiltration, espionage, and subterfuge. Read about Gorbachev's or China's plans and actions with infiltration agents in the US.
Bottom line is that Americans cannot stick their head in the sand and pretend like all these world problems can't hurt us. Will it largely impact how I cook my eggs in the morning, probably not...unless this whole gas stove stupidity changes that. But hey, I am intentionally not buying an EV because I've read and personally seen with my own eyes how corrupt and horrid that supply chain is for the earth and our own economy. So, yeah, there are decisions I make routinely that are impacted by the international environment.
However, just because you don't see a difference in your own personal day to day doesn't mean that there's nothing happening, or that personal decisions don't make a different. We ALL have blind spots. Some we choose, others we simply have for any number of reasons. Do not conflate your chosen personal blind spot with the reality of the world.
