| The first nation to achieve accurate mobile laser defenses with rapid firing that could shoot down ICBM's could take out the primary weapons of all of its enemies (and even friends). Chances are that its going to be the US. Should the US decide that China is going to be too powerful eventually then they could create some false flag events, possibly involving a regional ally such as Japan, that would give the US this power: 1. Nuke the entire country without reply. Not likely. 2. Force the Chinese government to scrap all nuclear weapons. Likely. 3. Force the Chinese government to not have a large standing army. Likely. 4. Force elections. Likely. Now rinse and repeat for Russia and anyone else. Every other nation would be forced to sign a treaty to not pursue laser weapons. Many countries would have to force their local populations to disarm. Now add in drones and you've got the US then able to continuously monitor and fly weapons of war over other sovereign states to "keep the peace". No need for land based robots when a drone in the sky could fire a laser instantly killing someone as soon as they show a gun. That's what I call complete dominance and control. |
In the modern era it's not possible to be completely safe from attack, the world is too interconnected. Our safety is partly dependent on the absence of major power vs. major power popularly supported animosity. A modern version of total war would not look like the WWII version of total war, or even the Cold War hypothetical WW3 version of total war.
Instead it looks like economic war, trade war, sabotage, cyber war, espionage, and guerrilla warfare/terrorism.
Want to hear a funny joke?
"How many lasers does it take to stop a nuclear bomb being exploded in a shipping container in the port of a major population center?"
...
"Give up? Here's the ans.." zzzzrt FLASH
The punchline is you're dead.
Want to hear a funnier joke? How vulnerable is our critical power, fuel, manufacturing, transportation, water, and emergency medical care infrastructure to sabotage? Here the punchline is: we're fucked.
You can't use laser weapons to conquer the 21st century Earth, at best you can use them as part of a deterrent. The moment you become a hegemonic asshole then you end up being a major target for asymmetrical warfare. Look at what happened with Russia vs. a teeny, tiny group of folks in Chechnya/Dagestan. Not only were tens of thousands of Russian troops killed in brutal urban warfare but hundreds of Russian civilians were killed by terrorist attacks within Russia proper. Chechnya has a population one one thousandth of China. Imagine turning China into a new Chechnya by attempting to conquer it with violence. Anti-ballistic missile lasers don't help with car bombs, they don't help with assassinations, or kidnappings, or sabotage.
Moreover, there is too much mutual self-interest against a major military confrontation between any of the major economies of the world for anything of the sort to be likely. The major conflicts of the 21st century are, as now, likely to be of a much different nature.
