That’s one of the reasons for the turbulent times. Let’s face the truth, most of the defense can easily be used for offense and given the state of online security every progress gets into the wrong hands.

Yes, many defensive uses of technologies can be used for offense. When I say defense, I also include offense there as I don't believe you can just have a defensive posture alone to maintain one's defense, you need deterrence too. Personally I'm quite happy to see many in Silicon Valley embrace defense-tech and build missiles (ex. recent YC co), munitions, and dual-use tech. The world is a scary and dangerous place, and awful people will take advantage of the weakness of others if they can. Maybe I'm biased because I spent a lot of time in Eastern Europe and Ukraine, but I much prefer the U.S. with all our faults to another actor like China or Russia being dominant

One could say that the unconditional support to the israelian policy in middle east since 1950 also brought it's load of conflicts.
The whole south America is fcked because of usa illegal intervention from WW2 to the end of cold war.
And the list goes on and on.
I mean it would be much faster to stay what good impact had the usa foreign policy on the world in the last 100 year.
It could have wondrously good impacts, but that only matters in a moral framework where good actions morally cancel out bad ones.
