My Lords, the noble Lord speaks with incredible experience of and insight into the work going on in defence and the JCPOA. Frankly, Iran’s escalation of its nuclear activities threatens not just stability in the region. Even putting the JCPOA aside, we have seen the steps that it is increasingly taking—for example, the explicit and direct support that it has extended to Russia in supporting UAVs, which have then been used in Ukraine—which demonstrate Iran’s intention not just to cause the suppression of its own citizens and cause instability in the region but to cause and fuel division and conflict further afield. The actions that it has taken recently put any kind of diplomatic solution highly at risk. We supported the JCPOA at a time when the previous US Administration pulled back because, even with all its faults, there was no other deal on the table. Last year, on two occasions, there was a big opportunity for Iran to sign the deal, but it did not do so. Recent actions make this much more difficult, but we are clear, which is why I stress the importance of working with our international partners, that we must do all that we can to prevent Iran from ever attaining a nuclear weapon.
