The American Tomahawk missile strikes against the Shayrat airbase are a justifiable response to an outrageous violation of international norms.
However I feel that they were too early and the US should have waited for an independent report into the Idlib attack on Tuesday to bolster its international case.
I do not think that the US or Russia want to get into a shooting war with each other and any Russian response will be through its Syrian proxies.
The ball is in their court. If the vile tyrant Assad uses these weapons again, then we should attack him again until he gets the hint.
Not intervening earlier was a serious mistake. This is now the least bad option.
