Nope. The UK only responded after its own territory had been struck, as had that of allies in the region who were not part of the US and Israel’s actions.

Its role has been entirely defensive, and legal under international law as part of the right to self-defence.

[megous]

UK started moving its military assets to middle east way before the war, was militarily acting in defense of aggressors and their allies from day one (and also in previous conflicts), and allowed to use its bases for bombing campaigns from the second day of the war, before their base was attacked. (announcement came before the attack, after Starmer got publicly called out by Trump)

UK got involved in bombing Iran even when attack on its base on Cyprus came from Lebanon and would have made more sense to attack the source of the attack if the goal was actual self-defense. That is if we accept the decision was in response to the attack itself, and not to pressure and public humiliation from Trump. Also Turkey also got under missile attack from Iran, and managed to use diplomacy/other means to de-escalate. So not joining the war was a possibility.

Instead of self-defence or helping stop the war, UK helped aggressors in making their attacks easier and deepened/prolonged the war that way, at great cost to the world. At a time when de-escalation was still possible, UK chose to contribute to the war on the side of the aggressors. Who knows why. Maybe they believed it would be a quick war or whatever and Iran would collapse quickly just like the countries UK decided to aggress against in the past like Iraq.

The UK moved assets into the area in defence of its own bases and in defence of allies like Gulf countries. The war was telegraphed, being at least a little prepared was logical. Even then, they had to rush deploy other assets like ships once the fighting started.

Similarly, permission for US aircraft to use British bases was given conditionally, allowing only strikes on Iran’s missile and drone infrastructure being used to target other countries, and was given after the war had begun and after the drone strikes on Cyprus.

Those strikes on Cyprus involved Iranian-manufactured drones provided to Hezbollah, an Iranian proxy, and the Islamic Revolutionary Guard Corps explicitly took credit for the strikes on Cyprus. So let’s not pretend this was some unrelated attack.

Notably, many other countries sent military forces to protect Cyprus too, including Greece, France, Spain, the Netherlands, and Italy, with Ireland even offering to join. Several of those countries were strongly opposed to the war and had denied the use of their airspace and bases to the US. Were they all ‘acting in defense of aggressors’ too?

Once again, it’s possible to both condemn the actions of the US and Israel in their violations of international law while also condemning Iran for doing the same. The illegality of one does not justify the illegality of the other.
