“While Israelis may hold dual citizenship, a Basic Law passed in 1958 states that Knesset members cannot pledge allegiance as parliamentarians unless their foreign citizenship has been revoked under the laws of that country,” the article states.
Another Israeli politician, who was elected at the same time as Svetlova is Rachel Azaria, who was also forced to renounce her foreign citizenship–in the US! Again from the Times of Israel: Azaria, a 38-year-old Jerusalem deputy mayor, renounced her American citizenship, which she had held by virtue of her mother having been born in the US.
It is astounding, is it not? Israel gets billions of dollars per year courtesy of US taxpayers–but anyone holding US citizenship is barred from serving in the Knesset! But we are not allowed to have a similar law here in the US banning Israeli citizens from serving in Congress!
