Speaking of "basic understanding," how about learning how to write a coherent paragraph?
It is too bad with people like you who never can comprehend anything and understand simple logic.
You can't read symposium , journals and other news reports which can be somewhat long.
Besides, you just can't come up with some little page of writing.
Even a simple sentence is too much in your feeling difficulty of interpretation by you.
Never will people have to babysit you to tell you what are all about.
Again, just for others, that was to illustrate some points:
(1) As it is a free world based on differences with variety of views, including the matter of extradition, US cannot push to demand Snowden back based on the logical judgment as rules.
(2) Snowden was working for a private firm and he was not exactly the CIA and others wearing uniforms , from policemen to MilITARY personnel, whereby demonstrated an example that KeLly MASSACRED civilians in Vietnam, as they are the ones in government who can commit gave offenses than those working in private firms.
(3) RADICALISM IS ridiculous and COULD LEAD TO GLOBAL DANGER AND WORLD VIOLENCES AND RADICALS as extremists do not know and live by rules and laws.
(4) US has no case fro Snowden, if any country wants to grant him asylum as whether he could be a defector or not, when countries believe no fair trial inside US. Besides, what other countries believe, that US is merely full of fakes by it's saying it has liberty, as too many people for doing no wrong, have been victimized by police, drones and even get to be charged in court from others making up falsehood.
(XYZ)= Your English is very bad to the bad degree of beyond having a dumb mind and not being able to comprehend contents. You are the biggest self-humiliated fool on the planet. Instead of self-acknowledging you are too defective and deficient in meeting the minimum standard, you show the low level of yourself. Simply as you can't understand basics, you are the queer element causing a lot of self embarrassment by speaking of yourself.
