Well Isis apparently operate within the UK and France judging by attacks done in their name, so bomb both countries, kill every muslim in both? What about the innocent people in the cities they will hide in, **** them too right. What about when 100k Isis fighters bury their weapons, can't be identified, America roles though for 5 years kills loads of people and they just start again when they leave.
What about when they cross borders and attack a different country and city because it's no longer safe for them in say Syria, blow up whatever city they go to in whatever country right?
Seriously, have you been in a coma since 2001, did you miss the failures that were Afghanistan and Iraq(in terms of suppressing terrorism, not their real goal). They INCREASED the numbers of people getting involved in terrorism both there and here so you want to do that again? Killing people just makes their family and friends more likely to join.
The only winners from another large scale military incursion are defence contractors and their bank accounts, everyone else loses, everyone, including all the soldiers we send and all the future English/American/French people who die as the result of someone who decided to join up because their family was blown up in the next war.
