Deductions & credits

For some reason I am being asked the same. For 2021 I have reported 107 Foreign tax credit, and for this year i have like 800. All this triggers the AMT. 

However, I  chose itemized deduction instead of Taking a credit i am not hit with AMT.  I lose the credit, but I don't have to deal with AMT.

Why should AMT be triggered by  such small amount? It looks like it is better to take Itemized Deduction at the end
