Mossad used the internet to access security cameras in Tehran and other locations enabling them to assassinate numerous Iranian politicians and leaders.
As someone who prizes my ability to determine my own destiny, and believing in my right and that of others to determine their own destiny, I oppose any entity that seeks to use force to impose its will upon others.
I do not know the extent to which Mossad may seek to obstruct my freedom of speech and access to information via the internet- perhaps it would depend upon how much of a threat they might see me as presenting?
