The United States has tried to fight in only one theatre of World War 3.0, focusing on achieving a quick, decisive defeat of Iran without engaging Russia and North Korea as adversaries. This is particularly difficult, given that Iran’s targeting intelligence is coming from Russia.
Iran’s threats to attack American targets in Europe could be made good. This would not be difficult for the Iranians, as long as they were not seeking to achieve significant destruction: a loud bang on a runway at Lakenheath or Ramstein would have to suffice. The US, which is mostly ignoring the targeting intelligence that has enabled Iranian munitions to hit American bases in the Middle East with precision, might have to notice the Russian source; and might be tempted to switch off comparable American intelligence provided to Ukraine.
Russian threats to attack the UK are already happening at low intensity: cyber attacks on supply chain and infrastructure targets have had some success. More of the same, including information warfare against Britain’s social cohesion, could exact a price from the UK for providing money, munitions and training to Ukraine. More desperate attacks against UK energy and internet infrastructure could sting more, without a dangerous move like shooting down an RAF aircraft or killing British soldiers across Russia’s borders.
Then there’s the change in US doctrine to shift the defence of South Korea from massive conventional force commitment to tactical nuclear battle. This week President Trump is making cosy noises to Kim Jong-Un while talking about cutting back on US-South Korean joint exercises, against the background of two nuclear powers going toe-to-toe upwind of Japan and uncomfortably close to northern China. This is necessary because the missiles that the US Army would have fired into North Korean depth, and the air defence missiles that would have shot down incoming North Korean munitions, have been used up in the Persian Gulf. It’s not that the US wants to use nuclear weapons to fight a tactical battle against North Korea, it’s that they’ve used up the other stuff.
Neither Russia nor Iran appears to be on the brink of collapse, however much damage has been done them. Putin appears to be ready to push on to Kyiv no matter how many North Koreans have to die in the process. (This is reminiscent of Iran sending Lebanese Hizballah fighters to die defending the Assad regime in Syria.)
The Iran theatre can end if the US steps back and gives the Iranians their win, swallows the Hormuz tolls, and gives Iran enough money to pretend to comply with restrictions on their nuclear programme. The Ukraine theatre can end if Russia steps back and accepts a cease-fire and negotiates itself out of Ukrainian territory. Both those solutions require Big Men to accept a measure of humiliation.
The US could treat the three adversaries as part of one conflict, but that would require the US to be a bit less friendly to Russia and North Korea. The alternative is to wait for the Big Men to retire, and just keep up the killing in the mean time.
