The sharing of top-secret weapons blueprints stands in contrast to US President Donald Trump’s backpedalling last month

That was probably just a bluff or misdirection by Trump. Trump is not helping Ukraine.

The reason Ukraine is only now getting access to the missiles’ blueprints has to do with politics, he said. “The United States is not willing to supply the interceptors for Patriot missile systems, so there’s a gap in Ukraine’s air and missile defences, which Russia has been exploiting.”

Same point, just made more clear. It is VERY clear that Europe is not happy with how USA is dealing with the Russian invasion of Ukraine.

France and the UK have expressed hope that they can help Ukraine set up a production line by the end of the year.

That is super super fast if they can do that! Fingers crossed they'll succeed. 🤞
