No- giving all the agency to Clinton ignores that it was a failure of the
entire international, and diplomatic community rather than just the President. A head of state is only as good, and as powerful as the system he's working within.
As people often forget the major military responsibility for stopping Rwandan should have rested with Belgium who had troops in the country, or France who propped up the Rwandan Government as it was a strong ally.
The responsibility lies with the UN- and by extension the UK/France/US who cut the UN peacekeeping force, and drastically reduced it's mandate.
No doubt HillGoose has an image of the US sending 100,000 troops in, and turning Rwanda into Baghdad circa 2003, but the reality is that US intervention wasn't need- it simply needed a stronger UN presence and troop funding.
Not a failure overall, but we should have intervened. Same goes for Obama and Syria.
Tbf all Obama's 2013 strikes would have done is take out a couple of airports, and command bunkers- it wouldn't have done enough to stop Assad.
