Maduro is bad. I don't really feel bad that he has been deposed. What will actually change now is a big question mark though. Seems the current government is just his stooges. Is this regime change or is this a hostage situation? Seems to me like Trump doesn't care about the suffering of the people of Venezuela as long as he can steal their resources, but that much is tbd.

On the other hand, what we saw is a President deciding to go to war without Congressional approval. That is profoundly dangerous. Congress exists as a check on the President's power and the Trump administration has been stripping back those checks at every opportunity. When one singular individual controls whether the country goes to war, we are treading on extremely dangerous ground. The people of Greenland undoubtedly feel that danger, but it is far from the limit of Trump's aspirations. When all is said and done, allowing any single person to maintain dictatorial control over our military is tremendously dangerous and is one of the clearest examples of this country's descent into dictatorship which should alarm every American (and pretty much everyone else too). 

People keep saying this, but it isn't exactly right.  The president can deploy troops without congressional approval, it had been like that for years.  It is something like the president can have 60 or 90 days for a conflict via the military, and no congress does not need to approve.

Example, Obama didnt tell congress he found Bin Laden.

Trump is a giant PoS, but we should be accurate, the president can and has deployed troops without congress for a long *** time.

Edit

See Korea, Afghanistan, Iraq and there is a 4th i can't remember.
