I pay tribute to my right hon. Friend for his incredibly important efforts engaging with the US. Obviously, the positions the US takes and the decisions it makes on support are a matter for the US Government and legislature, but my right hon. Friend is right to make the wider strategic point. Surely we are united on the need to have a deterrent against all the adversaries and threats we face around the world. I sincerely hope it will not be the case, but if Russia were to make much more progress and succeed, it would embolden other adversaries. He is right about the horrors of warfare. That is why we need to invest in our own armed forces and conventional deterrent, but above all to keep supporting Ukraine as much as we possibly can.
