It is illegal for the US to be fighting in Syria and anywhere else. Congress has declared no wars.
President Assad was popular in Syria before the US got involved. If the US wanted to go into Syria we should have had his invitation and supported him.
The same for Iraq and Libya. We should have supported Saddam and Gaddafi. Iraq and Libya were great places for Catholics to live when these men were in power. What they had in common is that they were not in debt to the world bank or the IMF. Now they are disaster areas. Catholics have lived in the territory now called Iraq since the Church began. Since the overthrow of Saddam they are practically wiped out.
The idea that any of these nations are or were threats to the USA is absurd. If the US had not gotten involved either there would have been no ISIS or Assad would have wiped out ISIS. Who do you think created and supplies ISIS?
"Collateral Damage" is a euphemism for killing innocent persons.
Venezuela is next. We should support the legitimate government not revolutionaries.
