First, Obama era holdovers still embedded within the White House and national security apparatus will claim that the national security process has been gutted and there’s no oversight and this was the President acting on his gut and whims against the advice of his advisors.
This, of course, ignores that these people think the President is too stupid to know who Suleimani is, but somehow he knew. Perhaps his advisors told him and made recommendations.
Second, talking heads on television will suggest this is all a way for the President to distract from impeachment by creating a rally around the flag effect.
Third, more talking heads and Democrat partisans will declare this is President Trump trying to start a war to win re-election in 2020.
All of this is super predictable and every bit of it will probably happen today on TV.
