Given history of mistrust + suspicion believed today that alliance between Br, US, USSR was marriage of convenience

  • solely an emergency arrangement against common enemy, Germany

Tensions between alliances grow during war

  • One of Stalin’s major concerns was immense pressure Soviet troops faced because of Germany’s constant attacks.
    • he urged US + Britain to quickly open a 2nd front in France to relieve this pressure + end war as quickly as possible

However US + Britain only agreed to open 2nd front through Op Overlord in 1944. Operation Overlord - D-Day, 1944 when they met a year earlier in 1943 during Tehran conference in Iran.

Stalin felt that allies were delaying opening of 2nd front to minimise their own losses + even weaken USSR!

  • deepened his distrust of US + Britain
