With all the brinkmanship, threats, and craziness in the news regarding DPRK and nuke testing, I for one really don't think this is heading towards a real nuclear war. No one benefits from 15 million people dying in the first day of any war. All sides - US, DPRK, Russia, and China get this. The fanatical goal of Kim Jong Un and his people, with the blessing of China, is to get the US military out of their backyard. The real game is control of Asia, and China wants to take that title from the US. I personally think that the US has painted itself into a corner, thanks to failed policies of previous presidents, and now the insanity of the current one. This may eventually leave the US with no choice but to negotiate, and may also result some day in sending the troops stationed in South Korea back home. The next US president, which is not favoring a Trump reelection, may get the honor of executing that task. The bottom line is that we now must face a future with North Korea having powerful nuclear weapons and having a feasible way of delivering them to a target.
The implications of this above scenario are far reaching, and one that would eventually have an effect on all countries in Asia, and possibly Australia and NZ as well. China would likely proceed with their version of Asian control, replacing the US who has been calling the shots - especially where borders and territorial claims are at stake. The other problem for the US, is its perceived invincibility if some small beleaguered country like DPRK calls checkmate. How many other fringe states would copy this strategy? I think the same scenario is brewing with Iran, especially in light of the 20 year Afghanistan affair. Iran wants the US out of there, and the entire region if possible. Could we see US troops packing their bags from Kabul in like fashion? Possibly, but much against the wishes of Israel I'm sure.
All of this has consequences for the US dollar - which I believe has been the core motivation for the past couple decades of "democracy" building around the world by US foreign policy (i.e. military, CIA, etc.). Anyone who has started talking about elimination of the dollar, hasn't fared very well. Go read the recent news on Venezuela. As Maduro keeps talking about dropping the US dollar, the US keeps talking about military intervention under the pretext of saving Venezuela. The US has almost $20 trillion in debt, and US dollar global hegemony is quite important to US politicians, and other US government entities. If countries stop using the USD for things like oil, gas, and other commodities, the US could lose control, and may have to deal with an unprecedented internal financial crisis and global power degradation. Imagine a world where the US can't apply sanctions that punish "misbehaving" countries, as the so called sanctions really wouldn't matter that much. This brings to mind the recent barter deal between Indonesia and Russia for MIG fighter jets. The US has sanctions on both countries for different reasons, but it didn't stop them from talking about another way of getting a deal done.
I'm not sure of the eventual impact the above scenarios would have on Indonesia, but would certainly affect (possibly in a positive way) large dollar based deals (e.g. aircraft, commodities, etc.). However, I don't think people in Indonesia would care for China rearranging sea lanes, and claiming small islands nearby as their territory - especially ones with a potential for oil and gas. There may be other long term impacts on Indonesia, but my crystal ball gets fuzzy at that point.
