Two years is very short in the US for serious crimes. The US has more people in prison per capita than any other developed country by a wide, wide, wide margin, largely in part because of the judicial system's willingness to hand down sentences for relatively minor crimes that would be seen as insane in most other countries.

For what she was charged with, two years is probably the bare minimum that was available at sentencing given the constraint of "must serve jail time".

Meanwhile in Germany, the sentence range for human trafficking is 6 months to a max of 5 years. Stealing a child is also max 5 years (if you're not intending to sell it).

The contrast is pretty stark.
