Of course. That's always been the case. From the Assyrians to the Greeks, Egyptians, Romans, the French of the late first millenium, the Chinese, the Indians, the Mayans, etc, all increased their power at the appearance of an external threat, extended trade routes, or war.
The threat of war with England created the union of states known as the Articles of Confederation in the colonies. The real threat of another war and economic collapse caused the Articles to be insufficient for the needs and tasks of the day, so a stronger union was created under the US Constitution.
The end of hostilities at the end of WW1 caused states to want to end war so they created the League of Nations, but it was too weak. Then after WW2, the states said enough is enough so they created a slightly stronger UN. And, today treaties, agreements tie together states as never before. Then came the internet. So now we have individuals connected from the lowest to the highest levels of society throughout personal, business, private and public enterprise.
Every crisis, whether economic, social, political, or military, causes the bonds that connect us to be strengthened beyond those previously established. If you do not want increased global connections, then I suggest that we prevent every single crisis and challenge before it starts - but wait, that's not possible.
So, we're stuck with this new world order, and the only real solution is to be part of the design of the systems that emerge rather than trying to pretend it's some prophetic apocalyptic prognostication being fulfilled.
