AFAIK, the US government doesn't recognize dual citizenships

According to the state department:

The U.S. Government recognizes that dual nationality exists but does not encourage it as a matter of policy because of the problems it may cause.

I *think* there's more to it than that, because of a rule change issued last year specifying that U.S. citizens must travel using a U.S. passport regardless of any other they might carry. Which is at least an implicit recognition. But beyond that, I got nothin'.

ETA: And in comes Hil with an actual answer.

US Dual Citizenship:

A U.S. citizen may acquire foreign citizenship by marriage, or a person naturalized as a U.S. citizen may not lose the citizenship of the country of birth.U.S. law does not mention dual nationality or require a person to choose one citizenship or another. Also, a person who is automatically granted another citizenship does not risk losing U.S. citizenship.

The U.S. Government recognizes that dual nationality exists

That sounds suspiciously reality-based. Are they sure they're talking about the U.S. government?

Great pictures of cat and mouse armor as worn throughout the ages: [link]

A blog described it like this:

The timeless battle between cat and mouse has gone through many iterations. Artist Jeff de Boer has brought some of this to life, creating armor worn by various warriors down through the ages. How many Toms and how many Jerrys have clashed on the fields of battle while wearing such as these? We may never know.

, a person who is automatically granted another citizenship does not risk losing U.S. citizenship.

I didn't think so, but I've heard so many different things. I knew of more than one person when I was in the military that had dual citizenship, so they could join either but for various reasons chose the US over their birth country. It may be that some of the other countries are who make the folks choose, US or them, and that's what I find confusing.

Yeah, the problem is that the US government now requires airlines landing in the US to report the nationalities of everyone on board. If the numbers don't match upon arrival, the airline gets heavily fined.

My cousin's daughter received US citizenship by dint of being of Native ancestry. Which is weird, because it's not like she was related to a First Nation that skirted the border, but people from Newfoundland.

I didn't realize lighter skin evolved to produce more Vitamin D.

Vitamin D is produced by the body (in a process involving cholesterol) in reaction to sunlight. In climes with less sunlight, darker skin is a disadvantage because it's better at protecting the deeper layers of skin from the ultraviolet light. Nature tries to balance it out, but we keep moving all around. Now we have light-skinned people who need SPF50 and dark-skinned people who need Vitamin D supplements.

Actually, we might all need supplements. Studies are showing that the optimal amount of Vitamin D, which may protect against certain cancers, is twice what most of us normally get from sunlight and diet, especially if we're protecting ourselves from the sun.
