Career Opportunity and Relocation: My ex-wife told me that she wanted to relocate to Europe for a few years, because she had been offered an excellent career opportunity in the international company she works for. She said they would pay her fares to visit Israel with our child every few months. I refused point blank and tried to dissuade her. However, I am still worried that she might try and bring legal action to gain permission. Could she succeed?

Yes, if the court decides in her favour, it can overrule any objections you may have.
