Inter service intelligence (ISI), Pakistan
they're scared of india. probably play russia and britain off each other since britain and russia have both been cock measuring over neighbouring afghanistan for almost two centuries. but pakistan along with india has fallen to chinese intelligence and political pressure.
Research and Analysis Wing (RAW), India
basically the same as pakistan but better funded and takes more initiative. pakistan v india, india comes out on top every time.
india is also more willing to learn. whereas pakistan is more arrogant but is a little more suited at playing people off of each other. however due to pakistans constant playing both sides off of each other nobody knows where pakistans loyalties are and thus won't share info as allies in the same way the west does.
Canadian Security Intelligence Service (CSIS), Canada
Australian Secret Intelligence Service (ASIS), Australia
both pretty similar. both off shoots of british intelligence. canada has pretty much 3 cities to its name whereas australia is still a little closer to britain in terms of military and cooperation. canada can surprise but they surprise for a reason. australia is more active in South East Asia. the steaks in SEA are more fruitful for british intelligence to share than what canadian intelligence can offer on the U.S.
The Bundesnachrichtendienst's (BND), Germany
don't know much about current german intelligence. but certainly they weren't to mess with during the Red Army Faction days. certainly germany is very intelligent economically and has historically proven itself time and time again to be a power house of intelligence and military.
Direction Generale De La Securite Exterieure (DGSE), France
france has been on similar levels to britain on and off. france certainly has a different style of doing things to england and it could be argued that they are not as good. however france did rise from wwii with a more aggressive agenda has climbed rapidly economically arguably better than england after wwii and has similar colonial links. however britain does have much more favourable territories like panama, egypt, kenya, nigeria, south africa, oman, yemen. so the uk has much higher control over the seas and trade links whereas france has more links across north africa and perhaps djibouti. but i think frances issues with such large immigrant populations has lead to better anti terror and surveillance and increasingly conflicting interests with america can, i imagine, have caused france to beef up its counter espionage.
Central Intelligence Agency, CIA, United States
the CIA is a neanderthal and a bully of other more sophisticated intelligence agencies. there is a review around the corner for the CIA since they have proven less effective than the FBI. proving budget does not always mean superior, training, technique or tactic. americas aggressive approach has caused it to become alienated intelligence wise. that does not mean they do not work with people. but for example when Vasili Mitrokhin turned against russia he went to the less violent nation of Britain with his Archive of files.
The Institute For Intelligence and Special Operation (MOSAD), Israel
Mosad are just a continental CIA. they are very good as a paramilitary force. but in terms of espionage and intelligence gathering are still not on parr with britain. they burn bridges almost as soon as they build them and get caught on numerous operations that they simply don't care about having made public. such as the assassination in dubai for one thing. they seize their first opportunity far too often and don't look far ahead enough.
Secret Intelligence Services/MI6, United Kingdom
one of the best. they have their fingers in a lot of pies. they are also very good at disposing of unneeded sources without burning bridges.
for example they had informants in the IRA and when they were done would often purposefully let them be exposed as an informant so that the IRA killed them. it would also mean that they don't have to pay them that "if it gets too hot we'll move you and your family out the country and put you in protection and we'll pay you a lump sum to live off as compensation plus payment for your efforts" money. they stand to be more effective than france. less messy than mosad and more diplomatically appealing than america. however even britains intelligence has not been a total winner. the IRA have proven themselves quite nifty against MI6. the IRA did after all fire an RPG at the ministry of defence from a park in 2000. and got away with it.
Federal Security Services (FSB), Russia
decrepit and malfunctioning. not what it used to be. resources are more increasingly going into GRU while FSB is being shrunk. the FSB is essentially the domestic GRU similar to what britains MI5 is the domestic MI6.
Main Intelligence Directorate (GRU), Russia
this is russias answer to the CIA. it is russia's big cock (as in rooster) on the block. while america might be more powerful in terms of brute force. russia is simply more creative and intelligent. where it lacks in budget it focuses on quality rather than quantity. its intelligence services have proven very robust against america during its height of power and also more increasingly guarding itself from its ever hungry neighbour china aswell as the british over in the pashtun region and northern middle east areas near the black sea.
so russia has a lot on its place and for what it needs to do does it very well. while america may be the white chess piece that always makes the first move, russia is the black chess piece that always makes an equally cunning response. while russia currently may be clashing with britain in regards to EU vs Russian Federation it has always had a frienemy relationship with Britain which we see with the Mitrokhin Archive and the Litvinenko assassination. it also seems that despite russias cold reputation it actually follows its bargains through and looks after its informants. whilst not necessarily very well, it still doesn't feed them to the lions like britain and america.
Ministry of State Security (MSS), China
the most silent of the giants in the intelligence world. and the most cunning, antagonistic and probing of the superpower that is america.
china is also sinking its fingers into india, singapore, japan, korea, taiwan, russia and africa. it leaves the least trace of the above intelligence agencies and as a communist nation also favours quality over quantity due to its limited budget.
most of the intelligence attacks on america are done by china. it has left a much smaller trace than russia (see litvinenko and mitrokhin) britain (see gibralta assassination, omagh bombing and loads more basically just IRA) and mossad (see dubai assassination).
