THAAD isn't effective against hypersonic missiles, which both Iran and even Yemen's Houthis now possess.

What do you make of this?

Doug Casey: War, in the long run, is a matter of economics. If you can't afford to fight a war, you'll lose the war. Missiles are now the preferred weapon for taking out enemy targets, and the only effective counter is anti-missile missiles. The problem is that both are brutally expensive. Can the costs be kept down, so war is more… affordable?

Generals, politicians, and "defense" contractors, however, love expensive high-tech toys. But if you're going to afford a war, the most cost-effective weapon is an ignorant teenage boy—something the Third World, especially the Muslim world, is awash in. They're cheap and stealthy delivery systems, far more effective than multi-million-dollar missiles. There's an endless supply of them, and they can be employed in a myriad of ways. From an economic point of view, it makes no sense for technologically advanced countries (like the US) to use ultra-expensive weapons to attack primitive countries, as we've done for the last 75 years.

Regardless of the weapons used, the thing to remember is that war amounts to setting wealth on fire. Missiles are about taking real goods, manufactured at great expense, and using them to blow up other real wealth; there can be a perverse logic to it. However, despite their rhetoric to the contrary, I'm not sure governments are too concerned about lots of young men dying. A surplus of unemployed young males is destabilizing, especially in poor countries.

Even a large country like the US will eventually collapse under the weight of war. That's much more true of the Ukraine. And vastly truer of Israel. Israel will further bankrupt itself shooting down missiles with ultra-expensive anti-missiles. With a gigantic debt load, enormous war expenditures and losses, living on welfare from the US, and no prospect of things getting better, the prognosis isn't good. About a million (it's said) of Israel's seven million Jewish citizens have recently made the chicken run, and those who remain aren't allowed to leave. I think Israel has a near-insoluble problem. Giving them more money and missiles won't help.

International Man: President Trump recently unveiled a plan to build a "Golden Dome" missile defense shield over the US, modeled loosely on Israel's Iron Dome. Critics question its feasibility, effectiveness, and cost. Independent analysts estimate the long-term price tag could reach $800 billion.
