This is a job for every indian.
Not for 'the government' or 'the space agency'.
As long as a two year old toddler can sit on the middle of a road crossing, with cars navigating around it, and no one picks it up, and calls 'authorities' or tries to find the mother, there is something seriously wrong in the attitude to live, other people, children etc. Nothing a 'government' can fix over night.
Same for a dead man lying on a road, all the passing people and car drivers consider him sleeping. Even if he is, what is the damn problem to get him off the road to the pedestrian side walks? No one cares about anything in india, only 'outsiders' care about corruption, that is so sad, it is not even funny!

The 'power' of the USD comes from the time when Nixon abandoned the 'gold standard' and forced the middle east to sell oil for USD only. So the dollar was more or less till the late 90s 'backed' by oil, the most important commodity of the world.
Otherwise the dollar has no power at all, hint: 85% of the world population pay their taxes not in dollar.
The idea that a currency has 'power' because you are 'forced' to pay your 'taxes' in it: is just ridiculous.

The Dollar in Russia? What a laugh!
If at all they use Euro or still: 'Deutsche Mark'.

Likely China, or Brazil.
A cirtual currency to, be used mainly by 'the rest of the world' but not so much by their own citizens (at least in the case of China).

Regardless of your beliefes: they are not.
They don't strive on 'catching more people' and no one forces the later comming poeple to make payments to the older ones.
It has absolutely nothing to do with a pyramid scheme.

Bremsstrahlung does not need vacuum.
How do you come to that idea? You have a fast moving particle and you "brems" it, slow it down, somewhere its energy needs to go. E.g. sending electrons in any material will slow them and produce Bremsstrahlung, that is how the phenomena was discovered.

Gamma rays are produced by many processes, not only nuclear fusion.

In this case they are very likely produced by simple ionization of gases and extreme acceleration of electrons. So, yes it is electric.

The distinction between X-Rays and gamma rays is not the way how they are produced but the energy level.

It is the same type of interaction like high atmosphere gamma rays that are produced by very high energetic solar wind particles.

Rofl, ever been there?

You have no clue at all.

Why would Chechnya "export" terrorism?

Sorry, seems you have not much clue. Chechnya is a nation that tries to separate from Russia.

During WW II the chechnic "terror attacks" would have been called "commando attacks", sure getting civilians as hostages in a theatre is a bit over the edge, but the germans, the spanish and the italian _REGULAR TROOPS_ did the exact same during WW II and the Spanish Revolution wars.

Perhaps that is one of the many reasons that all south americans hate you?

Anyway, was that law ever executed or "enforced" ... I can buy plenty of goods from Cuba in Germany, never noticed any restrictions the last 40 years.

A total trade embargo from the USA only, not from the rest of the world.

if you are into Rum you should treat it like a Whiskey and try the small (less known) distilleries like from Grenada and other small islands.

I have none in mind right now, but can ask a friend who is kinda an expert.

I doubt the US administration "realized" anything.

Very likely a conglomerate of US companies sees business opportunities and is pulling strings behind the scene.

There where no dire predictions made decades ago about present time.

You must have read an SF story and mix that up with predictions of scientists.

Well, I read it in german (for the first time) when I was 14. Which is like 35 years ago. I found it a nice story, I don't care about 'how a book is written' the more complicated the better, imho.
Obviously I read it several times when I was young, just don't know who in my family owns the book right now.
