Modern wars are bad for the economy, trade and making money.

 

Excepting a few arms dealers all sales of televisions, dvd players, furniture, houses, industrial supplies cease in an area afflicted by war. Also there is a lot of destruction of capital like buildings, machines that rot due to standing still, highly efficient staff being killed. And there is the fact that money spent on warfare is not spent on research, improving the economy, infrastructure, education.

 

 

 

Non sense scenario.

They would be no combat if such an alliance would like to prevent US to do that.

And UK would stay neutral.

Just at maximum leverage local resistance, Iranians, mine Gibraltar ? and avoid war.

And of course all muslims would react against that.
