However, I believe that for the sake of the contest and to avoid future problems …
Here's my opinion: the problems were made by countries and delegations when it was already too late.
At the beginning there wasn’t actually so much controversy. In fact, despite knowing Israel would participate. countries decided to participate too instead of withdrawing. And by that point, trouble started.
Especially when some countries selected their entry and all of a sudden, the specific participant suddenly started to criticize Israel‘s participation. But that is the artist‘s own agenda! Any other artist of the country would maybe not criticize Israel‘s participation.
Let’s bring up two different examples: Ireland and Iceland.
Ireland chose Bambie Thug and Bambie made trouble immediately after they were chosen. Their participation was used to turn it into a political agenda by Bambie. If Ireland did choose any other artist, the outcome would possibly be very different. Another participant wouldn’t have cared about politics and just participated because it‘s music they care about and not which country takes part.
Iceland even wanted a Palestine to participate! After it was announced Iceland went straight up to No. 1 in the betting odds. So you tell me this isn’t political? If he won he would have gone to Malmö with a political message. And also stirred the pot.
So why do these artists want to go there in first place? Why weren’t there louder voices in the beginning that country x did not want Israel to participate?
They were all fine with the EBU‘s decision. Maybe they weren’t happy about it but yet they participated.
It all started when somebody called out Israel, wrote an open letter against Israel‘s participation and asked other artists to join and sign. (Bambie). So why did the artist do that? It wasn’t necessary. If they wanted a statement, they would have withdrawn. But going and pressuring everybody to anti-Israel statements is a choice!
