By a VERY long way it is Russia, as you can see here.
More than twice as many people in Russia view Israel as having a positive influence compared with those viewing it negatively (35% to 17%).
The only other countries where the positives even outscore the negatives are India (21% to 18%) which, like Russia has its own problems with Islamic terrorism, Ghana (32% to 27%) and the USA. But the USA results are extremely concerning as it appears to be the most polarised - 43% positive but an incredible 41% of Americans regard Israel negatively. That is what years of main stream media lies can achieve.
The UK of course is one of the most anti-Israel countries in the world now - almost as anti-Israel as Turkey.
