Don't worry. It's only Moslems, I mean thugs, with bombs in Swizerland. Nothing to worry about in the USA.

Take off sarcasm goggles now.
Just don't say sorry when a major event occurs in the US. You had the advance warning and every reason to guess it is coming to America. And you chose to ignore it. Or blur the issue of terror with gun violence. Or given the choice, worry about shame over life. Like Obama.
These guys are several orders of magnitude more dangerous than a nut with a gun. If you give them the ingredients to blow up New York City, they will do it. Reacting once they have done it is too late.
The FBI directors says this: ISIS supporters have a social media "devil in their pocket all day long that says 'Kill, kill, kill.'"
How many ISIS supporters are there in the US? They have arrested dozens.
In November, 80% of Londoners were expecting an imminent major terrorist attack. Why would ISIS target London rather than Washington DC, say?
Watch Europe and learn from it. Don't pretend the US has different kinds of Moslems. The percentage of ISIS sympathisers is likely to be much the same. And ISIS just turned the international terrorism on-switch from off to on.
For myself, I want to winnow the dangerous population down to a manageable size in order to find the bad actors. If that means hurting some feelings, so be it.
