Okay, so uh there's a lot of things that can possibly be improved here.
First of all, I see that you've used full-stop after each clause. I believe a comma or a semi-colon would be better in this case?
RECOGNIZING the good intent of the original proposal.
STATING that the original resolution has very few arguments as to why specifically The Black Hawks is special and deserves to be condemned.
NOTING the original proposal makes vague claims without giving any specific examples.
BELIEVING that the original proposal has done more harm than good by giving The Black Hawks propaganda and recruitment material.
I would like to know the name and the number of the proposal you're trying to repeal here. Simply saying "the original proposal" isn't cutting it out for anyone since I'm pretty sure TBH had plenty of condemnation proposals before this one passed. And not everyone can infer which SCR you're repealing from the title alone, since TBH currently has two active condemnations.
STATING that the original resolution has very few arguments as to why specifically The Black Hawks is special and deserves to be condemned.
I would like to know what those arguments are and how are they lacking in making their case.
NOTING the original proposal makes vague claims without giving any specific examples.
Again, what are those arguments? How are they vague? What are they lacking?
BELIEVING that the original proposal has done more harm than good by giving The Black Hawks propaganda and recruitment material.
This can be worded significantly better, I believe. Perhaps make some reference to the contents of their recruitment telegram?
FURTHER NOTING that this is not a pardon of The Black Hawks' acts against defenseless founderless regions.
I don't think this clause is necessary, since no one's forgetting about TBH's acts anytime soon. They have two active condemnations after all
Therefore, repeals SC resolution #52 Condemn The Black Hawks
Someone correct me if I'm wrong, but I think it's illegal to end a proposal with anything but "Hereby" at the start of the ending clause. So it will be;
Hereby repeals the Security Council resolution #52 "Condemn The Black Hawks"
Honestly speaking, it's not good enough at its current state. It might reach quorum with an intensive TG campaign, but is sure to fall flat at the voting floor. I would suggest reading over SCR#52 again, see what specific arguments you can make against it. It might also help checking some previous successful C/C repeals and finding out what made them work. Good luck with the draft!
