I dunno. Before Snowden, a lot of nasty stuff that we now take for granted the intelligence community does, was seen as "tin foil hat." After Snowden, I no longer doubt the possibility of any realistically imaginable attack, ie, assume that if they have the physical ability to do it, you should assume they do it and are not stopped by any ethical concerns.
Our intelligence apparatus has cried wolf too many times, in terms of denying they do something and then it turns out they do it, to be trusted anymore. They've lost the benefit of the doubt and if they don't want people believing all the tin foil hat things, maybe they should stop doing so many of them.
America integrated large immigrant waves in it's past, and I doubt anyone would say the Italians, or Irish, or other minorities were not integrated today. Time bridges cultures, and we're the better for it.
For anyone interested in stories like these, I highly recommend "Normal Accidents" by Charles Perrow - there's an entire chapter on maritime accidents.
