An attack on the embassy is exactly the same as an attack on our mainland soil.
We ( or any nation ) can declare war, but on whom?
This appears to be a well organized gang, no one that I know of has said that this is state sponsored (or by Egypt, Libya, Iran, etc.). We we have information that it was sponsored by a nation, then let’s roll.
We did not declare war on Germany during the Reagan administration when the disco in Germany was bombed.
I hate to say this, but it’s like they critique that the gang is attacking a US installation because a couple of people within the US produced a movie they don’t like.
The fault here lies in our President and his team. If we stood strongly for freedom, and the gangs knew we would find them and kill them, this would not be happening.
