They lie blatantly by telling us that they are acting in western public interest.

It is not a lie if they are sincere. If use of these illegal weapons is allowed to become accepted and widespread, they will become available to terrorists and used against us.

There is a reason why the world agreed to ban their use.
Obama was right to make their use a red line.
You would not take this line if a Western nation flouted this ban.
You are just anti-Western democracy.
