i do not think so.
pros:
1) you can make much more money than in U.S.
2) most students in international schools are from U.S., which suggests you need prepare them for U.S.colleges. Actually, many students graduating from Internation schools in Shanghai went to ivory colleges in U.S.
3) you can rotate in different countries, which offers you different experiences.
4) you will be well connected with teachers, students, and their parents.
Cons:
1) you better like different cultures.
2) your students can be from rich families.
