Which issue was involved in both the firing of General Douglas MacArthur 1951 and passage war powers act 1973?

The issue involved in both the firing of General Douglas MacArthur in 1951 and the passage of the War Powers Act in 1973 was the extent of the president's power to commit U.S. forces to military action without the explicit approval of Congress.

- In the case of MacArthur's firing, President Harry Truman relieved him of command in Korea after MacArthur publicly criticized Truman's decision to limit the war to the Korean Peninsula and avoid a wider conflict with China. Truman argued that MacArthur had overstepped his authority and violated the principle of civilian control of the military.

- In the case of the War Powers Act, Congress passed the law in response to President Richard Nixon's decision to invade Cambodia without seeking congressional approval. The War Powers Act sought to limit the president's ability to wage war without the approval of Congress by requiring the president to consult with Congress before committing troops to a foreign conflict and to seek congressional approval within 60 days of such commitment.

Both of these events raised questions about the balance of power between the president and Congress in matters of war and peace. In the case of MacArthur, the president asserted his authority to relieve a military commander who was acting insubordinate. In the case of the War Powers Act, Congress sought to reassert its role in war-making decisions.
