"Palestine and Iraq"
Because (most) countries don't have the definite article in Arabic since they are proper noun. It's the same reason why we don't say "the Palestine".
Note that some countries have a definite article. Basically, if their names are not proper nouns, they have definite articles. For instance
- Yemen = اليمن means the right (opposite of left) in old Arabic
- Sudan = السودان means the blacks, as in the people who are black
- Irak = العراق means the origin
- Algeria = الجزائر means the islands (this is a special case, since the al- entered in the Latin name)
- Morocco = المغرب means the Occident
