Hope full no retard or zealot gets in charge of usa russia or china.......oh wait caugh(trump)caugh.
Trump is not as unstable as CNN tells you. If you think he is going to attack China or Russia you are hysterical. Get help.
But what about in the future....i still belive new weapons may make a nuke pointless like laser weapons
Lasers are replacements for small munitions such as bullets and missiles not nuclear weapons. Modern nuclear weapons can have a blast range of 150km and a death radius of up to 450km. Lasers require precision as a laser is a tight beam of light. To get a laser to cover that range is so beyond us that it is science-fiction. The replacement of nuclear weapons will be fusion weapons which will be far more dangerous. Hypothetically only one would be required to fry the planet as it would ignite the atmosphere and burn it away. Earth would be worse off than Mars
or better and more widespread use of iron domes ect?
Iron Domes work because Israeli is tiny and it's primary enemy is localized; Gaza and the WB. It is not hard to blanket any area within those confines. Also the enemy is primitive in comparison. The IDF has it's current enemies completely outmatch. For America, China and Russia it would would require a massive investment to cover the borders. Enemies are far more global due to aerospace and naval assets with payloads of nukes which has been the standard strategy for decades. All have ICBMs, air force and mobile ground assets. Besides most defense systems are deployed to protect military assets not the population. Major cities are death zones due to targeting and the willingness of the military to sacrifice the civil population to win a war. If NYC is required to be destroyed to win a war it is time to move.
Modern war strategy is based on Total War theory. Civilians are part of the military infrastructure due to taxes alone. You pay for the soldiers, pay for the workers making the weapons, for the resources used in construction, the food they eat, the clothes they wear, etc. You are also the replacements for causalities. In the nuclear war the Geneva Convention is just a fancy form of toilet paper. All bets are off.
