I"m not sure why when Trump is accurately criticized people revert back to HRC and Obama. The Red Line was a joke which cost Obama and the USA dearly in terms of credibility and standing. Also, when dems in Wisc. talked of recalling Scott Walker Obama indicated he'd have to get some "comfortable shoes" so he could walk along with the supporters of the recall. This energized the recallers who went into action and started the recall. They called Obama's people and asked him to show up, keep his word, literally, walk the walk. He never showed up, he dodged and weaved and left them hanging-more political bullshit.
Anyway, Obama is not president, he's not dog calling, he's irrelevent. The discussion was about our current president and how he looks like a fool. Obama's misdeeds do not give Trump any type of absolution.
