The difference between the first ch and second chh is that the second one is what we call 'aspirated'. This just means that air travels through your throat in the second one, whilst it doesn't in the first.
Say the word 'chips' (note how the focus of the mouth is in the front area)
Now say 'church' note how you clearly have air forcefully traveling through your throat area to pronounce this.
That's the difference.
Not really. People feel that Western countries are less corrupt, have better facilities and are more organised. You don't have to bribe every official to get your telephone/gas/electricity switched on. Furthermore, those who are not reserved candidates find that they miss out on educational and other opportunities and then are forced to look abroad to fulfill their career ambitions, resulting in a Brain Drain. But all this is undergoing a huge change due to 'Covid19' and things are moving swiftly due to development within India. Once these reservations are removed, India will provide more equal access to jobs/education based on merit.
There are many more recent cases than this. They have been using crisis management/actors to carry out all manner of terrorist attacks to further the NWO agenda. Some recent examples are 7/7, Charlie Hebdo etc. It seems to have worked for them for centuries but with social media, it is being exposed.
