Been happening since the dawn of mankind, except it use to be a lot worse than it is today. The price you pay each year to keep solving the disputes of all mankind. Thankfully the entire world is not at war.
Republicans want to keep disrupting society both here in America and around the world. Maybe you forgot about those wars started by Republican George Bush. Every nation in the world is trying to promote their voice, that is why diplomacy and free trade is the best way of solving all of these complex problems.
Engaging the world and working through the differences is always better than war. That takes a lot of work, and sometimes force is the only way to get someone to the bargaining table.
