Whatever Trump did or did not say to the Russian foreign minister and ambassador, the reaction right now is bizarre and out of all proportion. Many have said that 'if true' it has 'put American lives at risk.' I'm afraid I'm going to need to see a plausible scenario. One theory is that it will 'acclerate' isis's laptop-bomb program. That is just nonsense, and they publicly announced the threat and took security measures in March. If that didn't accelerate them..
And compromising a source in Turkey or on the battlefield is not the same as having an immediate battlefield or terror-threat-type effect. The people in the intel community and in the media who are talking this way need to calm down and report the facts, alright? They are making almost no definite assertions. They are also hinting at the completely incoherent theory that the Russians will leak back into isis, who will execute the source, let's say. As you try to look at any specific scenario, pay attention to the question of who you've got allied with whom, because the sort of thing they're saying makes no specific sense; they're just creating an amorphous cloud of emergency.
