One needs to learn that in life there are only two options: "You are either with us or with the terrorists" (George W. Bush).
Here is how that great German novelist, Thomas Maan, would have replied to Theresa May, Trump and Macron who have been "foaming at the mouth monotonous catchwords".
"This fantastic state of mind, of a humanity that has outrun its ideas, is matched by a political scene in the grotesque style, with Salvation Army methods, hallelujahs and bell-ringing and dervish-like repetition of monotonous catchwords, until everybody foams at the mouth. Fanaticism turns into a means of salvation, enthusiasm into epileptic ecstasy . . . and reason veils her face."
— Thomas Mann, “An Appeal to Reason” in The Berliner Tagg, October 1930
And did we get afterwards, an action of face-saving of imperialist powers who could not challenge the Russian regime, so they staged strikes for a show. Strikes hailed as "successful and perfect" and would save the "dignity of Europe". In fact, Western imperialism's option are very limited and almost paralysed not only because of Russia, but alos because if internal contradictions and crisis. In that context, we understand that Western imperialist violence is unable to stop or undemine the violence and the barbarity of the Syrian regime and its backers.
Unlucky are those Syrians who will get killed in the coming days and months. That's one of the ironies/predicaments of our age.
