that's correct.
but is that enough since "each transaction builds up a global web of intelligence which international partners are using to target you" ?!???
If you are careful enough? Yes. If you are not careful enough? Then no.
who are this international partners?
Anyone that wants to know who is using bitcoins and what they are using them for.
(i guess government agencies, feds, interpol)
Sure, those would probably be some of the organizations that are trying to figure it all out.
how it works the "global web of intelligence" that can "target you"?
There is a permanent record of EVERY bitcoin transaction that has ever occurred. Using forensic accounting practices, it is possible to analyze this "intelligence" and identify patterns. If people don't properly protect their identity and privacy, then it is possible to use the patterns in the transaction history to identify and target individuals and the people that they do business with.
a transaction is from A to B.
assuming A is super protective, how about B? what if B is already "target"?
If B is a target of investigation, and fails to protect their identity, then the organizations investigating B can question them. If B knows identifying information about you (such as your mailing address), then B can turn this information over to the investigation (or they may discover this information in records that B keeps). Then the investigation can identify and question you. This is why you should be very careful about what transactions you engage in, who you transact with, and what information you give them. It is best to avoid engaging in any illegal transactions no matter what method of payment you are using.
actually each transaction is a target
am i making sense?
No. What kind of "target" would a transaction be?
