There have been cases of Israeli citizens marrying terrorists to get them into the country. Though this law is an overreaction. It's one thing to do background checks and impose a waiting period on Palestinian spouses, but a total ban is ridiculous.
Don't agree with the headline or the law.
They aren't banning spouses, they are banning naturalization of them.
I don't know what other visas are applicable for Israel, in Japan if you get married you can get a spouse visa(1,3,5 year) but you won't be able to get a permanent residency right away.
1) Journalists at Reuters suck, 2) It's standard clickbait to drive traffic in, or 3) Journalists at Reuters purposedly oriented their article.
Whatever the explanation is for this debacle of an article, I don't like it.
