I think I started following PDF in either September or October 2007 but joined a lot later. My opinion is given below for listed countries and its citizens.
1- didn't know much about Pakistan or Pakistani citizens and their opinions but after joining I realize how beautiful your country is both geographically and Flora and fauna. Earlier thought almost all Pakistani citizens are extremely religious leading to extreme views towards other religion followers but now I believe many of you folks are really busy in your day to day life almost all Indians are here. Religious freedom wise bit negative, food wise top of the line. I also learnt here how many golden opportunity your country has lost in last 7 decades.
2- Afghanistan was bit negative but now hold positive views as I have met Afghan people personally. I believe Pakistani people have negative views towards them due to lack of people to people communication.
Middle easy- thought it was gold mine of oil, now I know it's terrorism den but native people are resilient and still fighting for freedom which is theirs.
Turkey - generally had positive views, now turning negative due to current turmoil and domestic policy in last few years.
CAR - had negative/neutral views, now very positive.
south east Asian- I had very positive views but now it's neautral for some, negative for some and for 4-5 countries it's very positive.
Far east - Japan and South Korea very positive views still same views. North Korea very negative views, still same. I had China views positive for great manufacturing industry, I thought on similar scale of European and Japanese tech based industry. Now it's negative knowing it's fully manpower based. Services industry very lower than my thoughts. Military same as earlier, its main driving force and extremely powerful on local areas.
Asutrailia & new zeland - good, now it's better.
North America- powerhouse if world, still it is but left leaning people getting mejority leading to corrosion in its keel. Loosing it's free values slowly slowly.
South America- far positive views, now it's coming down.
Africa - place filled with unmatched natural resources but incapable leadership. Same still but African Union is a standout.
Last but not the least SAARC countries - positive views of people, negative views of few government like Nepal Sri Lanka Maldives. I have people from these countries working with me and worked in last, very hard working but as per their tells, their local government depending on doles. Might not be 100 percent accurate but there is.
On overall note, I had generally good knowledge of world affairs, still improving.
Thank you all, good day!!!
A very humble advise from me
Never judge a nation or it's people by a handful of representatives in a online forum, Especially a defense forum where the majority will be "Defensive".. There are good and bad in every country and community, Humans are thought to be prejudiced in their own environment but we learn about each other as we expand our knowledge and i'm glad i joined PDF, It has expanded my knowledge and given insights to various subject matter other platforms would have not managed to, Truly Thankful
Btw and met atleast online some brilliant people, From all over, With varying opinions but equally great
I have met people from Sri Lanka and they tend to have a pretty good behavior and approach. Nice observation on them as most of them bust my local place in Sarnath.
