Yes, I know- as you write- that, "The Prime Minister has been very clear. that offensive troops aren't on the table."
However, how many times have you heard a politician, including Keir Starmer, begin a statement with, "Let me be very clear. Such and such won't happen."?
How many times, have you seen them keep to their word?
The answer, that even a 12 year old child could provide, is not many.
Now, here the PM says he is being very clear and you have repeated that assertion for him. He may mean it. He may not. He may be hopeful that what he is being clear about will come to pass.
But of course, in any situation and especially in a volatile one like this, it would be silly to simply believe what he is saying, to trust that this time a politician will stick to their word without any twists, turns or Jesuitical manoeuvres.
So, we can hope that there will be no offensive troops on the ground but unless this is your first time hearing a politician vow that they are being very clear and you have no experience of what usually happens when they are clear about something, then it would be foolish to trust them.
Sir Keir Starmer has no idea what will happen. They are short of troops in Ukraine-it may suit you to think that people have licked that fact off the floor but it is nonetheless true.
It will be very tempting for Zelensky to ask Starmer if his troops can be used offensively. Starmer may not give into th e emotional pressure that will be heaped on him and may say no but I, and many others won't fall flat on our backs if he says yes.
Finally, I don't know what will happen and nor do you but I think it would be failing in a public duty to refrain from pointing out to you that politicians lie.
