Nope. It’s hard to lose your US citizenship. The USA does not care if you are granted citizenship in another country by birth, adoption, or marriage. Who cares what laws the other country has about dual citizenship? Just because that country doesn’t recognize his USA citizenship does not affect his citizenship.
Obama became Indonesian, if he did, by virtue of his mother’s marriage. He was a minor. So he never had to apply for it or swear allegiance to it.
I didn't characterize it as "easy" or "hard". I'm simply saying what the law was, and in Obama's case describing it based on the statutes and case law prior to the 1986 statutory amendments, the time relevant to Obama. You seem to be repeating some talking points you picked up secondhand somewhere which are not accurate.

I NEVER SAID Obama had to apply for or swear allegiance when he gained Indonesian citizenship at the time of his adoption by Lolo Soetoro. Did you read my post? I'm referring to actions that might have been taken by Obama under Section 1481(a) of the INA and the cases interpreting that statute (again, prior to the 1986 legislative changes) that could have resulted in his expatriation in the late 1970s or early 1980s, long AFTER he would have gained Indonesian citizenship.
