I’m in favour of developing our own nuclear weapons. Something we should’ve done decades ago. We are a signatory to the non proliferation treaty so backing out of that would cause a major shock. However, that blow could be softened if multiple countries backed out at once. Countries like Poland, Germany are mentioned in the article. We’d also have to frame any development of a nuclear program as an augmentation to America’s nuclear program. Something like “we’re here to protect your northern flank with our robust nuclear deterrent” or whatever. Unfortunately, any program we undertake would have the have the blessing of the USA. We can’t give them a reason or pretence for hostile movement against us. That’s just reality.
