The reality is that when you are trying to sell at scale somewhere outside your domestic market (where your laws and rules run) muscle counts. The USA plays relatively nice, but be under no illusion you will find that the game is stacked against you. Your IP in particular is at risk from domestic actors.

An anecdote: I was once part of an exercise to evaluate the potential for an IP case in the USA to be won. One fun part was that there was a jury simulation. The jury were presented with the case and asked to vote. In the first round the jury voted unanimously for us. In the second round the jury were told that the defendant was a US company and we were a foreign company - and they unanimously voted for the defendant.

In other places you will find that you can't play the game - you can't get licenses to operate, your staff can't work there, your payments don't go through, you get a tax case against you, your staff suddenly fail to show up and it goes on and on.

If you are a USA company that happens less everywhere because the USA has power. People in important places owe the USA their lives, and if not then they have had lovely experiences in the USA. If you are UK company then you operate, now, under the reality that the UK hasn't got that power. World markets are open for the UK - but more or less to the extent that the USA decides that they wish to maintain that openness. Often that suits US interests in places where the UK has no interests and does not suit the USA in places that the UK has extensive interests in.

If you wonder why we are doing Aukus and have two big expensive and hard to defend aircraft carriers then the above is why. We are trying to pay the tariff that the USA wants to tolerate us as part of their system.

But it is the USA's system, cut and dried, over and out.
