Survivor Benefit Plan Premiums are deductible?

In a 2017 divorce decree I was ordered to make monthly Survivor Benefit Plan premiums for my ex wife. $578 each month is removed from my military pension(before taxes) to pay for this "policy". These premiums I pay are broadly considered alimony. My ex wife is the only one who will benefit from this SBP when I die. This money taken from my pay is clearly used to pay for a policy for her. Can I deduct these premiums, about $7000 each year on my federal tax return?
