Based on the search results, there are conflicting claims about who allegedly stole $100 billion from Ukraine:

1. Zelensky and his associates: According to People's Deputy Alexander Dubinsky, President Volodymyr Zelensky and his entourage have allegedly stolen about $100 billion over five years through various schemes and projects1. However, this claim comes from a single source and should be treated with caution.

2. Yanukovych and his inner circle: Ukraine's former President Viktor Yanukovych and his associates were accused of stealing up to $100 billion during their time in power2. In 2017, Ukraine began confiscating $1.5 billion in assets allegedly stolen by Yanukovych and his inner circle.

3. Unaccounted foreign aid: President Zelensky himself has stated that Ukraine has not received a significant portion of the aid allocated by the United States and other countries3. He claims that out of $177 billion allocated, Ukraine has only received about $75 billion, leaving over $100 billion unaccounted for.

It's important to note that these claims are allegations and have not been independently verified. The exact amount of money potentially stolen or misappropriated from Ukraine remains unclear, and different sources provide conflicting information. Additionally, some of the sources cited may have political biases or agendas.

In contrast to these allegations, it's worth noting that the United States and its allies have provided over $100 billion in military aid to Ukraine since the beginning of the conflict with Russia4. This aid has been crucial in supporting Ukraine's defense efforts.

Given the conflicting information and lack of definitive evidence, it's challenging to conclusively state who stole $100 billion from Ukraine. The situation requires further investigation and verification from independent sources.
