As the turn player, you will receive priority first upon entering the defend window (we're assuming there are no outstanding triggered powers waiting to be added to the chain). Assuming only the cards mentioned are in play and no other valid moves, you have one of two options: strike with one of your weapons, your pass priority.
If you strike with your weapon, your opponent can respond by playing Blink. At that point, you could then respond with Pummel to interrupt it. Or, your opponent can pass priority and allow your strike effect to resolve. After that, you receive priority once more and can either strike with your second Warglaive or pass priority. Assuming you pass priority, if your opponent passes priority then the defend window will close and your hero will deal 3 combat damage to your opponent's hero.
If you pass priority, your opponent can simply pass priority, at which point the defend window will close and no combat damage will be dealt.
