This article gives details on the many shortcomings that make the 'golden dome' idea unworkable. These objections have been around since Ronald Reagan proposed the idea in the 1980's, and they are even more true today. The 'golden dome' proposal deals with ICBM-type missiles, but they are already out of date. The 'golden dome' proposal has even less chance against hypersonic missiles that travel at Mach 20.
Ask yourself a question - The $175 billion 'golden dome' idea requires 36,000 satellites. Is there a certain South African at the center of the US government who might be pushing this idea, because he's the man who'll get a lot of that $175 billion to supply & launch them?
There’s no such thing as a “safe” nuclear war. If enough nukes go flying, it’s nuclear winter for the whole damn planet.
