Was Malta the most heavily bombed country?

Does Malta hold a record as the most heavily bombed country for its area?

Malta has a strong claim, but the exact wording and comparison need verification before it can be treated as a firm record.

The familiar description of Malta as the most heavily bombed country remains an uncertain statistic. Malta may have a strong case when bombing is measured against its small area, but comparisons with Laos or Vietnam depend on the wording and metric. The record claim therefore remains open pending research. The scale of Malta's air siege is clear even though its statistical rank is not.
