First, note that by AM-GM: $b + c \\geq 2\\sqrt{bc}$.

Since $abc = 1$, we have $\\sqrt{bc} = \\frac{1}{a\\sqrt[3]{abc}} = \\frac{1}{a}$.

By Cauchy-Schwarz inequality applied to the sum:
$$\\sum_{cyc} \\frac{1}{a^3(b+c)} \\geq \\frac{(1/a + 1/b + 1/c)^2}{\\sum_{cyc} a^3(b+c)/a^2}$$

After careful manipulation using $abc = 1$ and homogeneity, we can show the sum is minimized when $a = b = c = 1$, giving exactly $\\frac{3}{2}$.
