War is often justified through propaganda, but that doesn't make it right.
Definitely, the US government and the US media has proclaimed the so-called 'war on terror' as justified. However, it is neither a war, nor is it legally justified. This was a US attack and it is now it is an occupation of two countries. Calling this invasion and occupation a 'war' is nothing but pure propaganda and bunk. Fighting 'terror' is absolute fiction. These attacks and occupations have enriched the top 2% of the US while impoverishing the rest of the world.
Is war ever just? I don't think so. The path to peace is peace.
Truth and passive resistance can be a more powerful approach.
