Why Does The West Suck At War?

The West does love a war. It's people are usually against it, most of the time, but they many nations who always seem to be looking for a fight on the other side of the world. Sometimes it's about natural resources, and other times there's another excuse, like bringing democracy to a third-world country, whether they like it or not.
So, over the years Western armies have had many great opportunities to travel around the world, getting to know exotic places and being in contact with other cultures before bombing them but despite generally being overwhelming more powerful, they seem to suck at it.
If you were to look at the scoreboard of history, you might notice that the world’s biggest, baddest, most heavily funded military machines have a strange habit of walking into foreign countries, puffing their chests out, and then stumbling into a multi-decade quagmire that ends with them quietly backing out the side door.
Why do nations with hi tech satellites, smart bombs, sophisticated drones and enough military budget to fix every pothole on the planet constantly fail in wars with all the competence of a toddler trying to assemble a bookshelf without the instructions against groups of guys wearing sandals and carrying Kalashnikov's who refuse to accept them walking into their country?
The modern superpower’s favorite tactic as we saw in Vietnam, Iraq, Ukraine and Iran appears to be drop enough bombs, show off some  high-tech jets and the enemy will look at their subpar equipment, realise they’re outmatched and wave the white flag although nobody seems to explain this to the little guys who have a strange aversion to strangers telling them how to run their country.
When you bomb a village, you don’t usually create a loyal democratic ally, just a lot of people who are now very, very motivated to find a way to blow up your soldiers because as it turns out,  people defending their homes are significantly more motivated than people on a three-year rotation who just want to make it back with all their limbs still attached.
The West's peak hubris is deciding to topple a dictator and then install a new, shiny, democracy flavored government and head home in time for tea because the assumption is that the population on the receiving end was just waiting for a Western-style system to be delivered to their doorstep, or so they think but it turns out in almost every War this has been tried, you can’t just import Democracy and a lecture on why our way of life is superior.
There is also the problem of trying to save face once you have started a war, especially if you have invested thousands of lives and billions of pounds you can't really admit that the mission was a bit of a blunder so you keep going, the Afghan War lasted 20 years for these very reasons and the West may have broke a lot of walls and killed many people while making a lot of noise but in the end they slinked off whispering: 'Well, that was a disaster, let’s never speak of it again' when the people they went to war to remove, the Taliban, waved the West goodbye and moved straight back into Government again.
So why does it keep happening? Because the West are addicted to the idea that they are the Policemen of the world and refuse to accept that most of the world is perfectly capable of being messy, complicated, and defiant without them and despite the embarrassing defeat, five years later, they see a new conflict, rub their hands together, and say as they did in Korea, Vietnam, Iraq, Afghanistan, Libya and now Iran: 'Okay, surely this time we’ll get it right' but we know how that story ends because they never have and never will.
