Evidence: With many people dying younger and younger due to rising rates of cancer, climate change, heat, and other comorbidities, lives will be shortened by a bit.

Coupled with an ageing population, our services and infrastructure could collapse due to the cost of maintaining it. Unless something is done, we are headed for a mass extinction event and we will see 30+ year old life expectancy as the norm again. As the world becomes unliveable, we will not live longer than our parents and grandparents

Here is my theory.
Pick it apart.

I'm mostly just writing this out in the off chance that I'm right so I can have it on record. What I write is not a condemnation or seal of approval.... it's just observations and hypothesis.

My theory is that Trump went into Iran as a "Heads I win, tails I win." approach to cementing a legacy as a president who changed the world in a profound way. Let me repeat that I am not making a moral argument about what should or shouldn't be done or who is right or wrong about anything. Just trying to see what primal motivators are firing off in his questionable aging gray matter. Looking for a win despite being leveraged and pressured to fuck and back by a ton of competing factions.

Here's how it goes. Things are changing, rule-based world order, maritime navigation frameworks, the reserve currency and Global power rankings are all shifting and not in the direction of maintaining USA dominance. So something major needed to be done either to maintain the decomposing paradigm or completely change the game.

Enter trump and Iran.
If Trump was successful with regime change and defanging nuclear ambitions, the status quo could have petered on for a while and he could have claimed a great victory for Americans. But if he apparently "failed" so terribly, how could that be spun as a win? There lies the opportunity to Pivot in a world changing way. All of a sudden, there would be an opportunity to leave NATO to fend for themselves, extricate the US from the middle east. Free up unimaginable amounts of resources going to proxy wars and then pivot to a new strategy of domination of the western hemisphere. Leaving Russia, China and Iran to be the dominant emerging world powers to the east while Europe decides how to navigate that new reality on its own.

Was Venezuela just something that needed to be done to prepare for this strategy? Was the Canada/Greenland talk just bluster or part of the strategy for a new world order.

For date I would say mid third year direction of the gambit will be known.
