Are we heading to a world war?

With the US focusing a lot of it's energy on Iran and expending Billions of $ a day on ammunition, ($2.5M missiles being used to kill $30k drones) their focus has been taken away from Taiwan so it's unlikely that China will invade Taiwan for now but it's still not impossible if China sees an opportunity to take Taiwan without US Interference though Japan might have something to say about it. I don't think we'll see a "World War" where it's boots on the ground and Army vs Army any more, just look at Russia being unable to take Ukraine after more than 3 years, there are far too many drones and missiles being built so that may be the next major conflict and who knows who would win that type of non-nuclear War?
