Excellent speech by Hilary Benn
Didn't get what he meant about standing shoulder to shoulder with allies opposing ISIS ideology, given our MPs voted to stand shoulder to shoulder with our ally Saudi Arabia, which appears to have done little to crack down on Saudi private funding for ISIS and are also funding Islamist rebel factions, as they are more concerned about using all available resources to oppose Assad.
We also appear to be standing shoulder to shoulder with Turkey, who aren't successfully policing their borders against ISIS fighters slipping back and forth, and who oppose the Kurds more than ISIS, and who according to Russia (which claims to have satellite images) are the main consumers of ISIS black-market oil.

If ISIS lose territory, that is a propaganda coup but as in Afghanistan any territory gains against ISIS would have to be defended on an on-going basis.
I also agree with his point that we don't know how many ground troops are available to fight ISIS. Any ground troops are split into factions that are spread over a wide geographic area in Syria, many of whom are fighting each other as well as Assad (who claimed his regime to be the last stronghold for secularism in the region) and who are unlikely to trek over as Britain's "boots on the ground" to ISIS controlled areas unless it is in their strategic interests, as opposed to because Britain got upset because some French people were murdered.
Also, there are desertions from the Free Syrian Army due to tough battlefield conditions and the low pay not being enough to provide for fighters' families who need to be evacuated from their shelled homes. Meanwhile Islamist rebels who reject secularism and democracy but are fighting Assad and fighting ISIS are better paid, better armed, more fired-up on their Islamist ideology and are therefore able to drive out ISIS from certain areas where the FSA have failed to do so, and in the process help themselves to FSA supplies and weapons. Their superior prowess attracts more fighters to their factions - as not surprisingly militants prefer to throw their lot in with strong groups that at least have some chance of battlefield success due to better weapons, supplies, training and motivation.
So essentially, Hillary Benn seems to be saying it's better to do something military against ISIS, however small or symbolic, rather than do nothing, and there will never be a perfect time to deploy the air strikes, so why not now.
