The issue is to have a flexibility of options. A hypersonic fighter wouldn’t be flexible enough in some instances, also awfully expensive and could give a lot of time to enemies to do changes on the run if they discover to where is it flying.

Down here in Chile we are also starting to discover what El Niño is preparing to us:

As Chilean, my first big earthquake was the 2010 quake (8.8). And even if that wasn’t so big as in 1960 in Valdivia, that quake also created a significant tsunami that affected parts of the southern coasts. And even when people evacuated after the quake, many died when -because of some misinformation from local…

There was a plan in the Bush Administration about that, to put conventional warheads in Trident SLBMs, but they stopped it because the problems that could cause with other nuclear nations.

That is the CVN-71 Theodore Roosevelt in a shock test in 1987. I imagine that the bomb was designed to be be use only for that kind of test.

The announce was to calm some of the US allies, both strong (Korea and Japan) and weak ones like Philippines, about the commitment of the US military in that area.

The path isn’t totally random, because there are some persistent factors in our enviroment (temperature, presence of water, radiation from the sun, etc) that make more probable some process than others. Also, the more common is a gene across all species, the most probably it with survive.

But if all mammals disappear,…

There are two issues in the China - North Korea relations. The most immediate is if NK collapses, there would be a lot of refugees crossing the border with China, and they don’t want that.

Because it could bring a lot of unforeseen consequences, including North Korea attacking South Korea (and most probably, trying to focus the attacks on the capital Seoul, because is near to the border) and starting a war with the US and China.

Look, nobody likes him, but the main lesson of the Iraq War is that a…

If you define it as “fighting an enemy” the answer is yes, the US military is more capable than any other in the world to fight any enemy. Now, if you define it as “winning and enemy” the answer is depending of the kind of adversary. Is capable to win another army (as the Iraqui army) but no so to non-national groups,…

Yes, it would be incredible weird, with changes in form and color depending of the position of the objects (red/blue shift, like the Doppler effect in sound)

It would be problematic because the extra brain work to understand that. For example, our retinas require as little as one single photon to react or we could hear brownian motion, the random motion of particles. But, we have a threshold of all our senses (like the nociception, the perception of pain) to avoid but…

We only focus on the visual part of the images, but astronomers using the data can figure the position of every element of the picture (for example, how far stars are each other based on things like brightness and red/blueshift). Therefore, they can produce a model that is really near to the actual object observed by…

For start, you should blame every single president since Dwight Eisenhower and 1953 Iranian coup for the lack of long-term clear objectives. Or Ronald Reagan and supporting the mujahideen in Afganisthan against the Soviet Union, giving chemical weapons to Iraq against Iraq (that old times when Donald Rumsfeld was…

Do you think Saudi Arabia, one of the countries that supported ISIS against Syria, is a good country?

The US doesn’t lack will for what you said but because the Iraq and Afghanistan wars as an example of what not to do it.

DoD decides to close the gap with a new defense program, with lots of $100 million autogyros that can't fly until 2025 because they are overweight, they need a new helmet, it can't lauch missiles, etc, etc.

Many things:

There are some problems with your idea:

Same here in Chile: our taxation service (SII) gives you the possibility to pay almost any tax online, and if you have a fine for delayed taxes, you can discount a part of it if you only do it through the Internet. Its easy because all the banks are interconnected with the agency and the most common kind of bank…
