No, it wouldn't. A straight repeal of the War Powers Act also opens us up to another Vietnam. And amending it such that any use of force requires congressional approval would put us in an international straight jacket. From defending our shipping interests to protecting allies. In the event of China deciding it would rather just take existing islands to make it's "nine dashed line" a reality, we'd be arguing about immigration instead of deploying the Navy. And we would instantly lose the trade access we have to the entirety of the SEA region.
